StripSlashes

Anon

I tried using stripslashes($variablename); on my textarea form input box, but it kept refusing to work..

lets say i do this..
you have a textarea name of bob, and it contains "hey".

now when i say
print "$bob";
it prints this:
\"hey\"

so, I did this:
stripslashes($bob);
print "$bob";

It still did the same thing. What am I doing wrong?

Not sure, but I think you need to either

$new_bob = stripslashes($bob);
print $new_bob;

print stripslashes($bob);

Read the manual again. stripslashes() returns a modified string. It does not modify the original string. This is common behavior for PHP functions.

To change the value of $bob, do this:

$bob = stripslashes($bob);

Suppose if your string is like this

$string="don't";
In this situation if you print the value it will print don'\t something like that.

If you use stripslashes($string) then it will give the exact string you entered like
don't

Hope this helps

stripslashes() is a function, it returns a value- you have to catch that value in a variable, thus:

$newbob=stripslashes($bob);

Alternatively, if you wish to return the value directly into the original variable, you can do it this way:

stripslashes(&$bob);

you might wanna look that up tho, i rarely use it so the syntax might be wrong. It's in the Variables section of the php manual.

It is a useful and somewhat annoying feature of PHP that it will add slashes to HTML variables containing quotes. Useful if you want to feed the value straight into a database update. But annoying if you want to simply print it on another HTML document. If you have a PHP file with:
<FORM ACTION=test.php method=post>
<input type="text" name="val" value="<? print $val ?>">
<input type="submit">
</form>
and add a quote to the text field, then press the submit button, your field will be displayed as if addslashes() had been applied to the variable. Press submit again, and the original slash is slashed. Press submit again, and more slashes are added. And so on.
For "proper" behavior, your code must be:
<FORM ACTION=test.php method=post>
<input type="text" name="val" value="<? print stripslashes($val) ?>">
<input type="submit">
</form>
This behavior can be turned off using the magic_quotes_gpc variable. See also http://www.php.net/manual/en/function.get-magic-quotes-gpc.php for more information.
