I have read the other similar questions, but not found the answer, so here it is:
<?php
function load($page) {
echo "page: ".$page;
}
echo "
<script type='text/javascript'>
var page = 0;
window.addEventListener(...., function(){
var x = .....
......
if(x = ....)
{
page = page + 1;
var runQuery = '<?php load(page); ?>'
}
})
</script>
";
?>
The problem is that <?php load(page); ?> is not executed. If I write load(page); outside the echo, it works. Can anyone help me ?
Change the function to return:
function load($page) {
return "page: ".$page;
}
You're executing PHP with the echo so just use the return of load():
echo "
<script type='text/javascript'>
var page = 0;
window.addEventListener(...., function(){
var x = .....
......
if(x = ....)
{
page = page + 1;
var runQuery = '" . load($page) . "'
}
})
</script>
";

I'm incorporating PHP code into JQuery like this:
echo "<script type='text/javascript' src='https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js'></script>
<script type='text/javascript'>
$(document).ready(function() {
var count = ($('.data').length + 25);
/* This is the line */var c = $c;
$('#data').load('data.php?v=' + count + '&c=' + c)
$('.btn-data').click(function() {
count = count + 25;
$('#data').load('data.php?v=' + count + '&c=' + c)
})
})</script>";
The PHP variable shows as blue, there are no errors showing, but when I run it it refuses to work. I've tested everything else and I'm 100% sure PHP is the one causing the problem.
How can I fix this?
If $c is your php variable you will need to quote and join it inside an echo tag.
But as Carton (+1) said, is it a string, integer, object?
If it's an integer, this should work...
<?php
echo "<script type='text/javascript' src='https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js'></script>
<script type='text/javascript'>
$(document).ready(function() {
var count = ($('.data').length + 25);
var c = " . $c . ";
$('#data').load('data.php')
$('.btn-data').click(function() {
count = count + 25;
$('#data').load('data.php?v=' + count + '&c=' + c)
})
});
</script>";
If it's a string this should work...
<?php
echo "<script type='text/javascript' src='https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js'></script>
<script type='text/javascript'>
$(document).ready(function() {
var count = ($('.data').length + 25);
var c = '" . $c . "';
$('#data').load('data.php')
$('.btn-data').click(function() {
count = count + 25;
$('#data').load('data.php?v=' + count + '&c=' + c)
})
});
</script>";
If it's an object, you will have to parse the var or encode it.
Sometimes if you want to echo or return big blocks of html inside php, you can use an output buffer to capture the html, and then you can either return the html via a function, or echo it. This just makes your html easier to read when it's not wrapped inside echo quotes tags.
<?php
// c sting php var
$c = 'string';
// start output buffer
ob_start();
?>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
let count = ($('.data').length + 25);
let c = '<?=$c?>';
$('#data').load('data.php');
$(this).on('click', '.btn-data', function() {
count = count + 25;
$('#data').load('data.php?v=' + count + '&c=' + c);
});
});
</script>
<?php
// store everything between ob_start() and here into a php variable
$script = ob_get_clean();
// return script html
return $script;
// or echo script html
echo $script;
// not both together obviously
?>
I'm trying to populate a Drop-Down menu from a csv file located on a network share.
I've come as far to get the file to create all the options successfully when the file is in the wwwroot folder however, now I'm faced with the external url reference issue.
Ajax does not support local File:/// directories and when attempting to use the network share location it also fails: \\Server\Folder\File.csv
Is there any way to read the data from the csv file using php or other server-side language in order to perform my work on the data?
Code Below for your reference:
<script>
function SubmitBy(){
$.ajax({
url: encodeURI('./PrinterLookup.csv'),
success: function(data) {
var splitData=data.split("\n");
for (var i = 0; i < splitData.length; i++) {
var colData = splitData[i];
var strucData = colData.substr(0, colData.indexOf("="));
$('#SubmitBy').append("<option value=\"" + strucData + "\">" +
strucData + "</option>");
}
}
});
}
</script>
Looking for something like this,,, to bypass the ajax url limitation:
<script>
function SubmitBy(){
<?php
$Datapath = "\\Server\Folder\Document.csv";
$Data = file_get_contents($Datapath);
?>
var data = $Data;
var splitData=data.split("\n");
for (var i = 0; i < splitData.length; i++) {
var colData = splitData[i];
var strucData = colData.substr(0, colData.indexOf("="));
$('#SubmitBy').append("<option value=\"" + strucData + "\">" +
strucData + "</option>");
}
}
});
}
</script>
Any assistance on this will be greatly appreciated.
Thank you in advance.
in this line var data = $Data; you need to print $Data see below
<script>
function SubmitBy(){
<?php
$Datapath = "file:///Server/Folder/Document.csv";
$Data = file_get_contents($Datapath);
?>
var data = <?php echo $Data; ?> //correction here
var splitData=data.split("\n");
for (var i = 0; i < splitData.length; i++) {
var colData = splitData[i];
var strucData = colData.substr(0, colData.indexOf("="));
$('#SubmitBy').append("<option value=\"" + strucData + "\">" +
strucData + "</option>");
}
}
});
}
</script>
Please check first this is .php file .
If this is .php file.
<?php
$Datapath = "\\Server\Folder\Document.csv";
$Data = file_get_contents($Datapath);
?>
<script>
function SubmitBy(){
var data = <?php print_r( $data ); ?>;
var splitData=data.split("\n");
for (var i = 0; i < splitData.length; i++) {
var colData = splitData[i];
var strucData = colData.substr(0, colData.indexOf("="));
$('#SubmitBy').append("<option value=\"" + strucData + "\">" +
strucData + "</option>");
}
}
});
}
</script>
How to add var javascript value into id name ?
I have $i = 5; and var i = 2;
How to concatenate php var $i with javascript var i ?
I tried like this but not work.
$('#test<?PHP echo $i; ?>'+i).live('click', function() {
do something
});
and
$('#test<?PHP echo $i; ?>'+i+'').live('click', function() {
do something
});
How can i do that ?
var phpi = '<?PHP echo $i; ?>';
$('#test' + phpi + i).live('click', function() {
//do something
});
or if you want PHP $i + JS i for exmaple (3 + 2 = 5)
var phpi = <?PHP echo $i; ?>; // no quotes here as we need number
$('#test' + (phpi + i)).live('click', function() {
//do something
});
PHP echo makes some space so that might hamper the selector use it like this
How can I store only the value of f() into $ab?
How can I also change $ab dynamically in the loop condition when the button is pressed so that the integers are printed out dynamically?
<script type="text/javascript">
var i = 0;
function f(){
i = i + 10;
document.getElementById("more").innerHTML= i;
}
</script>
php
$ab = "<p id='more'> </p>";
echo $ab;
for($x=0;$x<$ab;$x++) echo $x . "<br>";
echo "<button type='button' onclick='f()'> > </button>";
Try this,
Hope this work for you.
<script type="text/javascript">
var i = 10;
function f(){
i = i + 10;
var html = "";
for(var j=0;j<i;j++){
html += j+"<br/>";
}
document.getElementById("more").innerHTML= html;
}
</script>
You need to send the variable $x to your function f
echo "<button type='button' onclick='f($x)'> > </button>";
Then in the function you can count how many times the buttons all together are clicked, i++:
var i = 0;
function f(x) {
x += i * 10;
i++;
document.getElementById("more").innerHTML= i;
}
I'm creating an UI in which the user will be able to change the texture of the selected object by clicking on the desired textures picture.
The problem is that I can only use the last texture added in the array.
Here is my php which lists the textures in my specified folder:
<ul id="textureH">
<script type="text/javascript">
texArray = [];
</script>
<?php
for($index=0; $index < $indexCount; $index++) {
$extension = substr($dirArray[$index], -3);
if ($extension == 'jpg'){
$texName = $dirArray[$index];
$texId = "texture". $index;
?>
<script type="text/javascript">
var texName = '<?php echo $texName ?>';
var texId = '<?php echo $texId ?>';
texArray.push(texId);
</script>
<?php
echo "<li id='".$texId."'><table><tr><td><img class='texture-image-list' src='img/" . $texName . "' alt='Image' /></td><td><span id='texture-item-name'>" . $texName . "</span></td></tr></table></li>";
}
}
?>
</ul>
And here's my function:
var uTexture = document.getElementById(texId);
uTexture.addEventListener("click", updateTexture, false);
function updateTexture(){
var texMap = "./img/" + texName;
for (var i in texArray) {
if ((texArray[i] == texId) && (SELECTED instanceof THREE.Mesh)) {
SELECTED.material.map = THREE.ImageUtils.loadTexture(texMap);
SELECTED.material.needsUpdate = true;
}
}
}
I think the problem comes from the array.
Thanks to 2pha I could achieve what I wanted to do.
Here's my new code:
(The php/html)
<div class="right-panel-textures">
<h3 id="cat-hierarchy">Textures</h3>
<?php
$myDirectory = opendir('img/textures');
while($entryName = readdir($myDirectory)) {
$dirArray[] = $entryName;
}
sort($dirArray);
closedir($myDirectory);
$indexCount = count($dirArray);
?>
<ul id="textureH">
<?php
for($index=0; $index < $indexCount; $index++) {
$extension = substr($dirArray[$index], -3);
$texName = $dirArray[$index];
$texId = "texture". $index;
if ($extension == 'jpg'){
?>
<script type="text/javascript">
var texName = '<?php echo $texName ?>';
var texId = '<?php echo $texId ?>';
</script>
<?php
echo "<li class='texture-single-item' data-texture-name='".$texName."' data-texture-id='".$texId."' id='texture-single-item'><table><tr><td><img class='texture-image-list' src='img/textures/" . $texName . "' alt='Image' /></td><td><span id='texture-item-name'>" . $texName . "</span></td></tr></table></li>";
}
}
?>
</ul>
</div>
(And the JavaScript)
var uTexture = document.getElementById("texture-single-item");
uTexture.addEventListener("click", updateTexture, false);
function updateTexture(){
$(".texture-single-item").bind("click", function(event) {
var nameT = $(this).attr("data-texture-name");
if (SELECTED instanceof THREE.Mesh) {
var texMap = "./img/textures/" + nameT;
SELECTED.material.map = THREE.ImageUtils.loadTexture(texMap);
SELECTED.material.needsUpdate = true;
}
});
}
Thank you :)
