Preg_Match Never Working

[Tenaciousmug]

I can't ever get this stupid function to work. I do it all the time and try to find other ways around it because I can never get ANY of mine to work.

And then I go to boards and copy theirs to see if they work and they don't.... so I really don't get what I'm doing wrong.

 

$depositamt = $_POST['depositamt'];
if (!preg_match("^[0-9]+$", $depositamt))

 

This is what I have. Well not the whole code, but you get what I'm doing...

[requinix]

PCRE expressions need delimiters.

'/^[0-9]+$/'

 

Also,

if (strlen($depositamt) == 0 || !ctype_digit($depositamt)) {

[Tenaciousmug]

Is that another way of doing it?

I really rather stick with the preg_match since I'm more familiar with it doing characters.

Is there any way to do this with preg_match?

 

And it does have an ending delimiter. That's the $...

Nevermind, I used the ereg() instead. (: Works so much better! Got it working.

Thanks though!

The code that requinix posted was for you to use in your preg_match() function instead of what you had. Nevertheless, glad you figured it out

Working until PHP6.. as ereg will be removed!

as is "DEPRECATED as of PHP 5.3.0"

 

If you know RegEx your be fine.. but by your questions i assume you don't know it,

 

$depositamt = $_POST['depositamt'];
if (!preg_match("^[0-9]+$", $depositamt))

 

should be

$depositamt = $_POST['depositamt'];
if (!preg_match('/^[0-9]+$/', $depositamt))

 

translated into English that says

if the following does not match

depositamt must have 1 or more number from the start to the end (nothing else)
