I am doing something like posting function in a local app it's开发者_开发问答 working fine really but it lacks with validation and not to mention the validation I made was a mess. I'm using jQuery oEmbed.
What I wanted is to print the illegal html tag(s) as is and activate/perform(I don't know the right term) the html tags I have allowed.
Any suggestions?
This is the best solution i came up.
First replaced all the < and > for html code then replaced back the allowed tags.
<?php
$original_str = "<html><b>test</b><strong>teste</strong></html>";
$allowed_tags = array("b", "strong");
$sans_tags = str_replace(array("<", ">"), array("<",">"), $original_str);
$regex = sprintf("~<(/)?(%s)>~", implode("|",$allowed_tags));
$with_allowed = preg_replace($regex, "<\\1\\2>", $sans_tags);
echo $with_allowed;
echo "\n";
Result:
guax@trantor:~$ php teste.php
<html><b>test</b><strong>teste</strong></html>
I wonder if there's any solution for replacing all at once. But it works.
