Edit, I fixed it by changing my JS to:
$('.zend_form input:not([type="file"]), .zend_form textarea').each(function() {
data[$(this).attr('name')] = $(this).val();
});
Hello,
As I posted earlier, I followed a ZendCast that allowed you to use jQuery to detect and display to users problem with their form.
However, file fields always return: fileUploadErrorIniSize (File 'image_front_url' exceeds the defined ini size" even if the file is within size limits.
TPL For Forms:
<?php $this->headScript()->captureStart(); ?>
$(function() {
$('.zend_form input, .zend_form textarea').blur(function() {
var formElementId = ($(this).parent().prev().find('label').attr('for'));
doValidation(formElementId);
});
});
function doValidation(id) {
var url = '/<?php echo MODULE; ?>/json/validateform/form_name/<?php echo get_class($this->form); ?>';
var data = {};
$('.zend_form input, .zend_form textarea').each(function() {
data[$(this).attr('name')] = $(this).val();
});
$.post(url, data, function(resp) {
$('#'+id).parent().find('.errors').remove();
$('#'+id).parent().append(getErrorHtml(resp[id], id));
}, 'json');
};
function getErrorHtml(formErrors, id) {
var o = '';
if (formErrors != null) {
var o = '<ul id="errors-'+id+'" class="errors">';
for (errorKey in formErrors) {
o += '<li>'+formErrors[errorKey]+'</li>';
}
o += '</ul>';
}
return o;
}
<?php $this->headScript()->captureEnd(); ?>
<?php
if (is_object($this->form) && $this->form->getErrorMessages()) {
echo $this->partial('partials/errors.phtml', array('errors' => $this->form->getErrorMessages(), 'translate' => $this->translate));
}
?>
<?php if (isset($this->errorMsg)) { ?>
<p><?php echo $this->errorMsg; ?></p>
<?php } ?>
<?php echo $this->form; ?>
Which is directed to
<?php
class Administration_JsonController extends Zend_Controller_Action {
public function validateformAction() {
$form_name = $this->_getParam('form_name');
$form = new $form_name();
$data = $this->_getAllParams();
$form->isValidPartial($data);
$json = $form->getMessages();
$this->_helper->json($json);
}
}
Example of returned json:
{"name":{"isEmpty":"Value is required and can't be empty"},"name_url":{"isEmpty":"Value is required and can't be empty"},"image_site_url":{"fileUploadErrorIniSize":"File 'image_site_url' exceeds the defined ini size"},"image_url":{"fileUploadErrorIniSize":"File 'image_url' exceeds the defined ini size"},"image_front_url":{"fileUploadErrorIniSize":"File 'image_front_url' exceeds the defined ini size"},"image_back_url":{"fileUploadErrorIniSize":"File 'image_back_url' exceeds the defined ini size"}}
I noticed a few people had this issue and they said that isValidPartial fixes it, so I changed
$form->isValid($data);
to
$form->isValidPartial($data);
but it didn't fix this issue.
Any ideas?
The problem is that you can't treat file fields in the same manner as regular text fields.
When you call $('input').val(), you get an actual text value for the text field, but for the file field you get the file name - and not the file contents.
Then your script tries to validate your file name as a file and, apparently, fails. In order for file validator to succeed you need to pass actual file contents to the script.
So, basically, you need to upload a file asynchronously to the server to perform all the necessary validations.
Unfortunately, uploading files via Ajax is not quite a trivial thing to do. Your basic options are uploading files via iFrame or swfObject. You can take a look at the broad selection of plugins suitable for this purpose here.
My personal choice for asynchronous file upload would be file-uploader jQuery plugin.
Are you putting an Encrypt type on your form?
I have found two different forum posts about this, including a stack post:
odd Zend_Form_Element_File behavior
You need to add enctype="multipart/form-data" to your form tag.
Basically what is happening is the form is using its default "application/x-www-form-urlencoded" method of encryption before it is sent to the server. File uploading is not supported with this method.

PHP creates the text from metadata from image file which stores it in variable of the same name of IMG source.
No Problems
JavaScript displays the gallery to show images, scroll & enlarge.
During enlargement it gives description of image from source attribute but always displays the text with � after every character. But PHP doesn't.
I've tried encoding which you will see from code & & echo header("Content-Type: text/html; charset=ISO-8859-1");
PHP:
$path = "gallery/";
$objs = new RecursiveIteratorIterator(new
RecursiveDirectoryIterator($path),
RecursiveIteratorIterator::SELF_FIRST);
$num = 0;
foreach ($objs as $pic){
$pic = str_replace('gallery/', '', $pic);
if ($pic == '..' or $pic == '.'){
continue;
}
$exif = exif_read_data("$DIR/gallery/$pic", 0, true);
$pic = str_replace('.JPG', '', $pic);
${$pic} = $exif['IFD0']['Comments']; ///// php Variable
echo "<script> var $pic = '".$exif['IFD0']['Comments']."';
var $pic = utf8_encode($pic);</script>";
// JS of variable of same name.
}
Sloppy but Works
JQuery:
$('#mSide').on('click',function(){
var src = $('#mPic').attr('src');
var v = src.replace('/gallery/','');
v = v.replace('.JPG','');
v = unescape(encodeURIComponent(v));
$('#fullPic').show();
$('#fullPic').append('<img class=\"fPic\" src=\"'+src+'\"
height=\"90%\" widdth=\"90%\" style=\"margin-left:0px;\" />');
$('#fullPic').append('<span id=\"picSummary\"
style=\"color:#FFFFFF;\" >testing <textarea > '+ window[v] +'</textarea>
</span>');
$('#fullPic').prepend('<input class=\"closeFullP headr\"
value=\"Close\" READONLY><br class=\"closeFullP\">');
});
Sloppy but Works and window[v] is the call

Never use utf8_encode() or utf8_decode() they make awful assumptions and happily/silently corrupt your data. Always use a function that allows you to explicitly specify your input and output encodings.
The data you're extracting from EXIF is encoded as UTF16-LE, and your page is... something else. I can't tell what and you should probably figure that out and be consistent.
Suggested reading: UTF-8 all the way through
If your page is encoded as ISO-8859-1:
$proper = mb_convert_encoding($input, 'ISO-8859-1', 'UTF-16-LE');
If your page is encoded as UTF-8:
$proper = mb_convert_encoding($input, 'UTF-8', 'UTF-16-LE');

I'we html code for the editor:
<div id="editor">
<h1>Hello world!</h1>
<p>I'm an instance of CKEditor.</p>
</div>
And javascript for it.
if (CKEDITOR.env.ie && CKEDITOR.env.version < 9) {
CKEDITOR.tools.enableHtml5Elements(document);
}
CKEDITOR.config.height = 150;
CKEDITOR.config.width = 'auto';
CKEDITOR.config.defaultLanguage = 'en';
CKEDITOR.config.language = 'en';
CKEDITOR.config.extraPlugins = 'uploadimage,filebrowser';
CKEDITOR.config.toolbarCanCollapse = true;
function loadEditor(id) {
if (CKEDITOR.revision === ('%RE' + 'V%') || !!CKEDITOR.plugins.get('wysiwygarea')) {
CKEDITOR.replace(id);
} else {
CKEDITOR.document.getById(id).setAttribute('contenteditable', 'true');
CKEDITOR.inline(id);
}
}
loadEditor('editor');
Can somebody give me a simple explanation how to make that i can upload image straight throw ckeditor. I've been trying over a week to do it. I downloaded plugins uploadimage, and it's dependencies plugins. No "Upload" tag appear in "Image Properties" window.
Thank you
UploadImage add-on only works for dropped or pasted images. If you only want Upload tab in Image Properties, you have to set config.filebrowserImageUploadUrl to a script that will handle the upload:
config.filebrowserImageUploadUrl = '/uploader/upload.php?type=Images';
Your upload.php should be like this (taken from Integrating CKEditor with a Custom File Browser, example 3):
<?php
// Required: anonymous function reference number as explained above.
$funcNum = $_GET['CKEditorFuncNum'] ;
// Optional: instance name (might be used to load a specific configuration file or anything else).
$CKEditor = $_GET['CKEditor'] ;
// Optional: might be used to provide localized messages.
$langCode = $_GET['langCode'] ;
// Check the $_FILES array and save the file. Assign the correct path to a variable ($url).
$url = '/path/to/uploaded/file.ext';
// Usually you will only assign something here if the file could not be uploaded.
$message = '';
echo "<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction($funcNum, '$url', '$message');</script>";
?>
I copied the code from a YouTube tutorial, modified the database connection and SELECT items to connect to my existing DB, but I can't seem to get the JS to load the PHP file. In Chrome using the "inspect" tool, I can see that the JS file is loading, but when I click on GRAB on my HTML page, it doesn't do anything. Almost like the JS file is loading but not running.

PHP File
First try to add a console.log('something') inside your javascript click function, right before the var name =... line, to see that your event is even firing. If not you need to register the event properly. Is the click function surrounded by
$(document).ready(function () {
$('input#name-submit').on('click', function() {
var name = $('input#name').val();
if ($trim(name) != '') {
$.post('ajax/name.php', {name: name}, function(data) {
$('div#name-data').text(data);
});
}
});
});
//try using submit event
$(document).ready(function () {
$('input#name-submit').on('submit', function(e) {
e.preventDefault();
var name = $('input#name').val();
if ($trim(name) != '') {
$.post('ajax/name.php', {name: name}, function(data) {
$('div#name-data').text(data);
});
}
});
});
I'm not sure why my PHP code was edited and removed from here, but I've ended up re-writing the whole PHP page. I added or die(mysql_error()); to my SELECT statement and found that it needed me to specify my database in the FROM. I have multiple databases on my server and even though the DB is specified in the connection string it needed it again in the SQL Statement. The next problem I resolved was removing the mysql_num_rows as this was just not working like the demo did.
ORIGINAL PHP
<?PHP
if (isset($_POST['name']) === true && empty ($POST['name']) === false) {
require '../db/connect.php';
$query =mysql_query("
SELECT 'names'.'location'
FROM 'names'
WHERE 'names'.'name' = '" . mysql_real-escape_string(trim($_POST['name'])) . "'
");
echo (mysql_num_rows($query) !== 0) ? mysql_result($query, 0, 'location') : 'Name not found';
}
?>
The original was far too complicated for what I wanted and also for me to problem solve it so I re-wrote it:
NEW PHP FILE
<?PHP
//I've intentionally left out the connection data..
$sql_select = mysql_query("
SELECT names.location
FROM database_name.names
WHERE names.name = '" . $_POST['name'] . "'
")
or die(mysql_error());
$sql_fetch = mysql_fetch_assoc($sql_select);
echo $sql_fetch['name'];
?>
Thanks to those that assisted. Appreciated...
I am aware of the deprecated tags in the PHP file, but when I was copying from a demo so I wanted to get it working before updating it with new tags.
I'm new to jquery and ajax. I'm trying to get my first ajax script to work, but it's not working and I need some assistance, please.
I have a php page that is supposed to post to another php page, where the latter will do some processing and get some files to get zipped and download. The user needs to input a starting and ending date, and the second php script will use this information to prepare the data. This functionality works perfectly fine without jquery, but doesn't work when I add jquery.
What do I want to achieve? I want to post in the to the same php page and get the post output in a <div></div> tag.
My first php page contains (downloadPage.php):
<script src="https://code.jquery.com/jquery-1.11.3.js"></script>
<form action="doDownload.php" method="post" id="dateRangeID">
<input id='time1' class='input' name="datefield1" style="text-align:center;"/>
<input id='time2' class='input' name="datefield2" style="text-align:center;"/>
<input type="submit" value="Download Data" name="submit" id="submitButton">
</form>
<div id="result"></div> <!-- I would like it to post the result here //-->
The second page (doDownload.php),
<div id="content">
<?php
if(isset($_POST['submit']))
{
$dateVal1 = $_POST['datefield1'];
$dateVal2 = $_POST['datefield2'];
if($dateVal1 != $dateVal2)
{
header('Content-Type: application/zip');
header('Content-disposition: attachment; filename="file.zip"');
$fullListOfFiles = $downloadFullTmpFolder.$filesList;
$command = "sudo $ldlib -u myuser /usr/bin/python3 $downloadScriptFile -datadir $gnomeDataDir -time1 $dateVal1C -time2 $dateVal2C -outdir $downloadFullTmpFolder > debug_download.txt 2>&1";
$output = shell_exec($command);
$fp = popen('cat '.$fullListOfFiles.' | sudo -u myuser zip -# -9 - ', 'r');
$bufsize = 1024;
$buff = '';
while( !feof($fp) )
{
$buff = fread($fp, $bufsize);
echo $buff;
}
pclose($fp);
}
else
{
echo("<p>Dates have to be different in order for the download to start.</p>");
}
}
else
{
echo("<p>Error: Page called without submit.</p>");
}
?>
</div>
Finally, the jquery part in downloadPage.php, which if I add it doesn't work anymore (which I'd like to learn how to do right, and I mainly learned from the manual of jquery, the last example in the link)
<script>
/* attach a submit handler to the form */
$("#dateRangeID").submit(
function(event)
{
event.preventDefault();
var $form = $(this),
t1 = $form.find("input[name='datefield1']").val(),
t2 = $form.find("input[name='datefield2']").val(),
subm = $form.find("input[name='submit']").val(),
url = $form.attr('action');
var posting = $.post(url, { datefield1: t1, datefield2: t2, submit: subm} );
/* Put the results in a div */
posting.done(function(data) {
var content = $(data).find('#content'); // <--- So this turns out to be wrong. Right is only $(data);
$("#result").empty().append(content);
});
});
</script>
What is wrong in this? Please assist. Thank you.
If you require any additional information, please ask.
Looking at the obvious, you have:
var content = $(data).find('#content');
where, you're trying to find an element with the ID content in one of the following results:
<p>Dates have to be different in order for the download to start.</p>
or
<p>Error: Page called without submit.</p>
To simplify the problem, all I want is passing 3 variable from javascript to PHP. So let say I have 4 varible : a,b,c,message.
I have tried the following ways:
1)The code below is in my javascript file
window.location.href="somewebsite.php?x=" + a + "&y=" + b + "&z=" + c + "&msg=" + message;
I saw that it actually passing the values to URL, it jump to the PHP website that specifies in the code above but somehow nothing is getting from $_POST['x'] ( I even try $_GET['x'] and $_REQUEST('x') but none of them works at all)
2) Then I tried with ajax
$.post("somewebsite.php",{x:a, y:b, z:c, msg:message})
And same as above nothing are passed to the PHP website.
3) I tried with form submit
I put everything into a form and submit it to the PHP website but what I get from $_POST is an empty array.
So I conclude that something is wrong with azurewebsites server. This is the first time I used window azure so I don't know how it even works. Any suggestion would be appreciated.
you can try out ajax function
$.ajax({
url:"url",
method:"post",
data:{x:a, y:b, z:c, msg:message},
success:function(data)
{
// success code
},
error:function(error)
{
// error code ;
}
});
Should work:
Your js file:
$(document).ready(function(){
var aval = "testas";
var bval = "testas2";
var cval = "testas3";
var msg = "testas4";
$.post('test.php',{a:aval,b:bval,c:cval,message:msg},function(resp){
alert(resp);
});
});
php file should look like:
<?php
$resp = "";
foreach($_POST as $key => $val){
$resp .= $key.":".$val." \n";
}
echo $resp;
?>
After post alert should give response of all sent post values.
I hope it helped you. If yes, don't forget resp. Thanks.
Try sending an array to your somewebsite.php write this inside a function on jquery code.
It must work if you place it on a good place on your code.
var x=new Array();
x[0]='field0';
x[1]='field1';
x[2]='fieldN';
$.post('somewebsite.php',x,function(x){
alert(x);
});
Your somewebsite.php could be like this.
<?php
if(!isset($_POST['x']))$x=array();else $x=#$_POST['x'];
for($i=0;$i<count($x);$i++)
echo "X ($i) = ".$x[$i];
?>
Happy codings!
