I have a jQuery script embed into a webpage that I am scraping with Tampbermonkey and It works well but it is posting back to my server the entire body of the html.
Embed into an html page that I am scraping has this code:
jQuery(document.body).append("<iframe id='somenewtab' name='somenewtab' />");
jQuery(document.body).append("
<form action='https://example.com/test.php' target='somenewtab' id='form_submit_data' method='post'>
<input type='hidden' name='data' id='submit_data'><input type='submit' value=''></form>
");
jQuery("#submit_data").val( btoa(unescape(encodeURIComponent(document.body.innerHTML) )));
jQuery("#form_submit_data").submit();
The script grabs all the html and then posts it to php script where it parses the data.
test.php
$data = base64_decode($_POST['data']);
$dom = new DOMDocument();
$dom->loadHTML($data);
$select = $dom->getElementById('portfolio');
My question is, is there a way to only post the body of the html without all of there head information or better yet only post back whats inside the getElementById('portfolio') tag? The data in the id tag is the only data I need to parse.
Currently it posts everything in the html webpage and the server is getting bogged down with the POST limit size.
you can use wrapper based on "simplehtmldom" project available on Sourceforge and get the text/html of the dom element, and can post it.

I am creating a website backed by a database. I have created my forms that collect the information but now i need to read in the input from the form when user clicks submit and process it for mySQL. I am having my form action be a new page but I can't figure out how to read in value from the previous page. My Form code looks like this:
<div data-wrapper-react="true">
<span class="form-sub-label-container" style="vertical-align:top;">
<input type="text" id="first_3" name="q3_fullName3[first]" class="form-textbox validate[required]" size="10" value="" data-component="first" />
<label class="form-sub-label" for="first_3" id="sublabel_first" style="min-height:13px;"> First Name </label>
</span>
When user hits submit the action for this page is connect.php. I am not sure how to read in the value there. I tried this following command:
document.getElementById("first_3").value;
This just displays the code on blank html page for connect.php and not read in the values. The data from the forms needs to be processed into different tables if someone can help with that as well that would be great. Thanks
Form handling, in the way you are describing, is something you do server-side. PHP is handled on the server first where PHP tags can be evaluated to HTML, then this is returned to the browser. You would not handle form input from javascript, until after your PHP has done something with it. Here is a refresher: https://www.w3schools.com/php/php_forms.asp
<?php echo $_POST["q3_fullName3[first]"]; ?> would output the value into the HTML page allowing you to do something like this:
console.log("<?php echo $_POST["q3_fullName3[first]"]; ?>");
If you view source of the HTML, you will notice the PHP tag is gone and replaced with the form field value.
It sounds like you might want to get a book about PHP + MySQL since interacting with a database is a more advanced topic. I can recommend this one:

I am required to send data from an html page, via input elements to a php script and I cannot use ajax for some reason. How to accomplish this?
My code is something like this:
HTML:
First Name : <input type"text" name="first_name">
<br><br>
Last Name : <input type"text" name="last_name">
<br><br>
<button id="submit_btn">Submit</button>
Now, I want the javascript to be something like :
function redirect_from_here() {
close(); //close the current window
window.location='./phpfile.php'; //load the new page which will process the data sent to it.
}
My question is how do I send the value in the input elements in the HTML portion, as data to be processed, to the php script (phpfile.php in this case).
Please note that I prefer not to use html form for doing the job.
You are using HTML form as there are input fields in you code.
Inputs are part of a form and should be wrapped by a form element
Why using JS for submitting the form when you can use <form action='script.php'.. for that?
I suggest that you revise your requirements instead of trying to come up with a hackish way of how to send the data..
Just submit a form with action="phpfile.php"
if not interested with html,
then in the window location bind the values as a GET form method do
I have a html web page which I use to get some user input. This input is then posted using jquery to a php script which in turn sends a get request to a REST API to receive json data.
My question really is: is it possible to change my php file into another webpage with embedded php and redirect to this while posting the variables to the same script, so I could display the json results in a table on a new page simultaneously.
I already receive the json in the javascript file and I know I could use this to create a table, I was just interested if I could in fact do it all in one go on the php page as I already have script written to populate a table using the json data.
I have included some basic fragments of my code to help explain what I am doing.
HTML:
<head>
<script type="text/javascript" src="collect_User_Input.js"></script>
</head>
<p> What is the unique id of the beacon? </p>
<form> <input type="text" id="uniqueId" /> </form>
<button onclick="collect_User_Input();" >Send Request</button>
JS:
var uniqueId = document.getElementById('uniqueId');
$.post("send_Request.php", { uniqueId: uniqueId.value },function(result) {
alert(result);
PHP:
$uniqueId = $_POST["uniqueId"];
(GET request using curl)
echo ($uniqueId);
I tried skipping the javascript step and submitting the form directly, but this always gave me forbidden error messages. as you may have guessed I am very new to this so any advice is welcome.
In your PHP you will most likely want to return some JSON using json_encode:
http://php.net/manual/en/function.json-encode.php
Within your JSON, you could return a success value - then depending on the value of that you can redirect using:
window.location
You could even have a second attribute that returns what page you want the user redirected to if it isn't the same as the uniqueID:
{"success":true,"location":"/your/path/here.html"}
The flip side being, if there is an error you can return this to your page with a relevant message:
{"success":false,"message":"ID not found"}
I use this process to check something is valid on the server before doing the redirect, which sounds more or less the same as what you want to do?
I have nicEditor wysiwyg editor in my page (textarea tag) .
I want to send the output of the code editor to php page by ajax , this is my request .
You can do a php require to include any type of file:
textarea.html:
<textarea>
//htmlcode
</textare>
page.php:
<?php
//php code
require "textarea.html"
?>
is that what you are talking about?
Or are you refering to using javascript to get html code from the file?
i don't know exactly how nicEdit works, but according to nicedit.com, it just changes all <textarea>s to rich html editors. I'm guessing you can still refer to the textareas the same way, which would by to do what #atlavis said:
<textarea id='text1'></textarea>
<script>
var textarea document.getElementById('text1').value;
textarea = escape(textarea);
//now send textarea to the php with a XHR request
</script
