Question

I have the following code

<input type="text" id="chapter" name="chapter" value="'.$chapter_title.'"/>

I want to add stripslashes to the ‘.$chapter_title.’

Would I do something like this.

<input type="text" id="chapter" name="chapter" value="stripslashes'.$chapter_title.'"/>

How would I do this – not too sure where to put brackets etc.

Your question is much clearer when you post the whole line. The HTML is part of a string:

$some_string = '<input type="text" id="chapter" name="chapter" value="'.$chapter_title.'"/>';

It doesn’t really matter that it’s HTML for this question, so let’s make the example shorter:

$some_string = 'abc ' . $chapter_title . ' !!!';

That’s better. Without HTML’s double-quotes, it’s much clearer what’s going on. The string $some_string is the string 'abc ', concatenated to the PHP variable $chapter_title, concatenated to the string ' !!!'.

In fact, any PHP expression will do, not just an expression. In this case you want to concatenate the value of stripslashes($chapter_title) rather than just $chapter_title itself, so:

$some_string = 'abc ' . stripslashes($chapter_title) . ' !!!';

Putting the HTML back in:

$some_string = '<input type="text" id="chapter" name="chapter" value="' . stripslashes($chapter_title) . '"/>';

There is plenty of great recommended reading on PHP. I suggest picking up a book with good reviews and going through it. Twice.
