output_add_rewrite_var

(PHP 4 >= 4.3.0, PHP 5)

output_add_rewrite_varAdd URL rewriter values

Опис

bool output_add_rewrite_var ( string $name , string $value )

This 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. Please note that absolute URLs (http://example.com/..) aren't rewritten.

This function's behavior is controlled by the url_rewriter.tags php.ini parameter.

Зауваження: Calling this function will implicitly start output buffering if it is not active already.

Параметри

value

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>

Just to clarify...

session.use_trans_sid does NOT need to be enabled in order for output_add_rewrite_var() to work.
