How to transfer text box from page to another page - php

Question

I am new to php and I need some help.
I have two sites. And I want to display text box from my edit.php on index.php.
<form method="post">
<textarea name="content" cols="40" rows="5">
Enter your comments here...
</textarea><br>
<input type="submit" value="Submit" />
</form>
<?php
$content = $_POST["content"];?>
How do I transfer variable $content to my index page?

Answer 1

To address your comments. (Don't down rank me... his original question was not precise).
// on your edit page
<form method="post">
<textarea name="content"></textarea>
<input type="submit" />
</form>
// when you submit your edit page
$filename = '/mytextarea.txt';
$content = file_put_contents( $filename, $_POST['content'] );
// on your index page
$filename = '/mytextarea.txt';
$content = file_get_contents($filename);
if( ! empty( $content ) ){
echo '<div>'.$content.'</div>';
}

Answer 2

From edit you want to make sure your action points to index.php
edit.php
<form method="post" action="index.php">
<textarea name="myTextBox" cols="40" rows="5"></textarea>
<input type="submit" value="Submit" />
</form>
In index.php, you can access the variable with $_POST["myTextBox"], this can be outputted as text or as a value in the example below. Be sure to use htmlentities when including the value back with a form field, this will prevent "injection hacking".
index.php
<?php echo $_POST["myTextBox"] ?>
<form method="post" action="index.php">
<textarea name="myTextBox" cols="40" rows="5"><?php echo htmlentities($_POST["myTextBox"]); ?></textarea>
<input type="submit" value="Submit" />
</form>

Answer 3

Well, just set the action on the form to the page you want it to post to - example:
Random Page:
<form method="post" action="/index.php">
<textarea name="content" cols="40" rows="5">
Enter your comments here...
</textarea><br>
<input type="submit" value="Submit" />
</form>
Index.php:
if(isset($_POST['content']) && !empty($_POST['content'])){
echo htmlspecialchars($_POST['content']);
}
At least I think this is what you are asking?
If you are echoing a random textbox to a page, make sure to sanitize it using htmlspecialchars()

Answer 4

Try to action your form to your index.php :
<form method="post" action="/index.php">
</form>
With that, once you submit your form, your page index.php will be loaded, with values of your form in $_POST.

Answer 5

// on your edit page
<form method="post" action="index.php">
<textarea name="content"></textarea>
<input type="submit" />
</form>
// on your index page
if( $_SERVER['REQUEST_METHOD'] == 'POST' ){ // This will prevent the textarea from
// being shown unless some form posted to this page
echo '<form method="post">
<textarea name="content">'.$_POST['content'].'</textarea>
<input type="submit" />
</form>';
// If it's not set or it's empty, then it just won't show anything....
// you don't need to check for that unless you want to set a value when it is empty
}

Just change your form to post to the second site instead of to itself, then echo the $_POST['content'] on your index.php page
www.firstsite.com/edit.php
<form action="www.secondsite.com/index.php" method="post">
<ul>
<li>
<textarea name="content" cols="40" rows="5">Enter your comments here...</textarea>
</li>
<li class="submit">
<input type="submit" value="Submit" />
</li>
</ul>
</form>
www.secondsite.com/index.php
<?php echo $_POST['content']; ?>
