Textarea Value Not Getting Posted with Form

Textarea value not getting posted with form

try to put it inside the form tag as follows... it should work

<form action="sendConfirmation.php" name="confirmationForm" method="post">
    <textarea id="confirmationText" class="text" cols="86" rows ="20" name="confirmationText"></textarea>

   <input type="submit" value="Email" class="submitButton">
</form>

however you can use the same approach as well but you need to provide the from id attribute then

<form action="sendConfirmation.php" id="confirmationForm" method="post">
   <input type="submit" value="Email" class="submitButton">
</form>

Textarea not posting value in form

Always ensure you test that the submit button has been clicked before accessing the values of your form fields using the isset function. This is because as the server load the page the server attempt to retrieve the value of the inputs field which have not yet been entered. as such undefined. Another solution is to use another page to handle your form submission.

    <?php
    if(isset($_POST['submit'])){
     $age = $_POST['age'];
     $description = $_POST['description'];
    }
    ?>
      <form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">
        <div class="form-group">
          <input name="age" />
          <label>Description</label>
          <textarea name="description" rows="4" cols="50" class="form-control" value=""></textarea>
          <button name="submit" value="save">Save</button>
        </div>
      </form>

Textarea doesn't keep its contents after a form submission

The main problem you are facing is that you are POSTing to a different script, and then doing header("location: index.php"); back to index.php. This loses all $_POST vars, and there is no way to add them into the header redirect (browsers POST, not server header redirects).

So, you need to change your direction...

Since you are already stuffing the textarea content in a session variable $_SESSION['Text'], you can use this on your index.php:

<textarea name="TextArea" ...otherstuff... ><?php 
      echo (!empty($_SESSION['Text']) ? htmlspecialchars($_SESSION['Text']) : '' );
      unset($_SESSION['Text']);// optionally clear after re-iterating it
?></textarea>       

Some caveats you need to address in your ProcessText.php page though:

• Move session_start(); to the very top before any html or echo output.
• Add session_write_close(); before your header();exit;.
• Heck, all that 'html' above your header() needs to go as well.

If you don't want to use sessions... because some expert told you they are terribly unreliable and useless:

A) POST to the same page that will be re-displaying your form (ie index.php)

or

B) Setting up a main branch script which handles all submits, but has no html of its own. This then would do a straight include('index.php'); of which page you should be given (thus the $_POST vars will exist). However this method requires a bit of planning and discipline in setting up all your scripts and html blocks.

textarea values not posting with form

You cannot post form elements with disabled attribute. Instead use readonly on them. Eg:

<textarea id="sources" name="sources" readonly>

And you can style them like disabled using CSS:

[readonly] { /* style as disabled */ }

Or, have a same name with hidden <input /> fields:

<textarea id="sources" name="sources" disabled>
<input type="hidden" value="^ textarea's value" name="sources" />

Cannot get the value of a textarea via post method

It is because you need to name the textarea:

<textarea name="txtcomment"></textarea>

The id parameter does not have anything to do with how forms work (with the exception of labels, but that is not important here).

Unable to post the content inside my textArea which is inside the form which sends POST REQUEST

So I found a solution to my problem in this post:
Here

What I needed to do, is to add a form id="composeForm" to my form and then use that same id
inside the textarea(attribute: form="composeForm")

HTML

<form action="/compose" method="post" id="composeForm">
<div style="margin-bottom: 1rem; margin-top: 2rem;">
    <label for="exampleInputEmail1" class="form-label">Title</label>
    <input type="text" name="postTitle" class="form-control" id="exampleInputEmail1" aria-describedby="emailHelp">
</div>
<div>
    <label class="form-label" for="textAreaExample">Post</label>
    <textarea name="postBody" id="textAreaExample" cols="150" rows="10" class="form-control" form="composeForm"></textarea>
</div>

<button type="submit" name="button" class="btn btn-primary" class="mt-4" 
style="margin-top: 1rem;">Publish</button>
