For a completely valid XHTML document you have to set the arg_separator, use this before you use output-add-rewrite-var:
<?php
ini_set('arg_separator.input', '&');
ini_set('arg_separator.output', '&');
?>
(PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)
output_add_rewrite_var — Add URL rewriter values
$name, string $value): boolThis function adds another name/value pair to the URL rewrite mechanism. The name and value will be added to URLs (as GET parameter) and forms (as hidden input fields) the same way as the session ID when transparent URL rewriting is enabled with session.use_trans_sid.
This function's behaviour is controlled by the url_rewriter.tags and url_rewriter.hosts php.ini parameters.
Note that this function can be successfully called at most once per request.
Note: Calling this function will implicitly start output buffering if it is not active already.
nameThe variable name.
valueThe variable value.
Returns true on success or false on failure.
| Version | Description |
|---|---|
| 7.1.0 | Before PHP 7.1.0, rewrite vars set by output_add_rewrite_var() use the same Session module trans sid output buffer. Since PHP 7.1.0, dedicated output buffer is used, url_rewriter.tags is used solely for output functions, url_rewriter.hosts is added. |
Example #1 output_add_rewrite_var() example
<?php
output_add_rewrite_var('var', 'value');
// some links
echo '<a href="file.php">link</a>
<a href="http://example.com">link2</a>';
// a form
echo '<form action="script.php" method="post">
<input type="text" name="var2" />
</form>';
print_r(ob_list_handlers());
?>The above example will output:
<a href="file.php?var=value">link</a>
<a href="http://example.com">link2</a>
<form action="script.php" method="post">
<input type="hidden" name="var" value="value" />
<input type="text" name="var2" />
</form>

For a completely valid XHTML document you have to set the arg_separator, use this before you use output-add-rewrite-var:
<?php
ini_set('arg_separator.input', '&');
ini_set('arg_separator.output', '&');
?>This function also adds a parameter to <input type="image"> fields!
Example:
This code:
<?
output_add_rewrite_var ('var','value');
echo '<form action="" method="post">
<input type="image" src="image.jpg" alt="go">
</form>';
?>
will output something like this:
<form action="" method="post">
<input type="hidden" name="var" value="value">
<input type="image" src="image.jpg?var=value" alt="go">
</form>
