[SOLVED] preg match hidden field

[waynewex]

I need to scrape out the value of a hidden field.

 

The field name will be like so:

 

<input type="hidden" value="9337700952" name="MemberId"/>

 

The only thing that is different each time is the value.

 

Any help would be appreciated.

Tried the following but I get a blank screen.

 

$pattern = '/<input type="hidden" value="([^"]*)" name="Checkit"\\/>/';
preg_match($pattern,$this->result,$match);
print_r($match[0]);

Why are you double escaping the forward slash? And are you sure that exactly

 

<input type="hidden" value="..." name="Checkit"/>

 

appears in the haystack?

 

Your sample data says MemberId, so is Checkit right? Also be sure the cases match, or add the pattern modifier i after the last slash in the pattern to make the search case-insensitive.

Hi. Tbh, I'm guessing here. I'm just trying to use code from other examples.

 

Here's what I have:

 

$pattern = '/<[^>]*name="Checkit"[^>]*value="([^"]+)/';
preg_match($pattern,$this->result,$matches);
array_shift($matches);
print_r($matches);

 

It just printed "Array()".

 

Here's what I found in the source ($this->result)

 

<input type=hidden name=Checkit value=35806834>

Ok. I'm getting somewhere:

 

$pattern = '/<[^>]*name=Checkit[^>]*value=([^"]+)/';
preg_match($pattern,$this->result(),$matches);
array_shift($matches);
print_r($matches);

 

It matched ok, but it also took in the code after it. So I got value=8934782348> <img src

 

Etc

[waynewex]

Its ok! I got it!

 

$pattern = '/<[^>]*name=Checkit[^>]*value=([0-9]+)/';
preg_match($pattern,$this->result(),$matches);
array_shift($matches);
print_r($matches);

 

Woop! Thanks for your help!

Great, was about to suggest that change

 

But beware that your pattern also would match something weird like

 

<div weirdname=Checkitvalue=12345

 

If the syntax in your source doesn't change, I would probably go with something simple like

 

~<input type=hidden name=Checkit value=([0-9]+)>~
