Notepad++ - Replace all $_POST elements that don't already contain strip_tags()

Question

Is it in any way possible to replace all single PHP $_POST['diffentOnEachPage'] elements with strip_tags($_POST['diffentOnEachPage'])

Around 50% of my $_POST elements already contain strip_tags() but some don't.

What would be the best way to approach this without finding each one and adding strip_tags() individually? - Ideally using Notepad++

Answer 1

Alternate way would be to remove it from everywhere and just do

foreach ($_POST as $key => $value){
   $_POST[$key] = strip_tags($value);
}

Answer 2

Since you already have occurrences of strip_tags($_POST['baz']) you need to be careful not to add strip_tags to those. To do this you'll want to do negative lookbehind for 'strip_tags' and only replace the remaining instances.

Another catch - $_POST['foo'] wrapped inside a different function - you'll want to preserve the trailing ) when wrapping.

This should do the trick. I'm sure this can break in a number of other ways, but someone smarter than me can fix that :)

I tested this on Notepad++ 6.5.1.

Find what:

(?<!strip_tags\()(\$_POST\['.*'\])

Replace with:

strip_tags\((\1)\)

Input:

$_POST['foo']
strip_tags($_POST['baz'])
another_function($_POST['bar'])

Output:

strip_tags($_POST['foo'])
strip_tags($_POST['baz'])
another_function(strip_tags($_POST['bar']))

Answer 3

Use search and replace.

Search (\$_POST\['.*'\]) and replace by strip_tags(\1)
