PHP Wiki Like Function

[eli311]

Hi,

 

So im trying to make a php function that turns [[img:testimage.png/Img]] to and url to the image.

 

e.g.

from: [[img:testimage.png/Img]]

To: http://www.mytestsite.com/images/testimage.png

 

Here is the string to change: Change this to an URL [[img:testimage.png/Img]] And this one [[img:testimage1.png/Img]]

 

Here is the PHP Function:

$string="Change this to an URL [[img:testimage.png/Img]] And this one [[img:testimage1.png/Img]]";

function findImage($string){
/* The Var's */
$Image_found 		= false;
$ImageName 		= array();
$mystring			= $string;
$Image_Start   	= '[[img:';
$Image_End   		= '/Img]]';
/* The Var's */
/* Find if the Img tags are there */
$ImageCount1 		= substr_count($mystring, $Image_Start);
$ImageCount2		= substr_count($mystring, $Image_End);
/* Find if the Img tags are there */
/* Find out where they are */
$WhereImage_Start 	= strpos($mystring, $Image_Start);
$WhereImage_End 	= strpos($mystring, $Image_End);
/* Find out where they are */
/* If the counts equal the same continue */
if($ImageCount1 == $ImageCount2){
if ($WhereImage_Start !== false && $WhereImage_End !== false) {
	$Image_found = true;
}
/* Start the loop */
if($ImageCount1 >= 1 && $Image_found == true){
for($i=0;$i<$ImageCount1;$i++){
	$Find_image = substr($mystring, $WhereImage_Start+6, ($WhereImage_End-6)-$WhereImage_Start);
	$replace = IMG_LINK."/$Find_image";
	$search = "$Image_Start$Find_image$Image_End";
	$mystring = str_replace($search, $replace, $mystring);
}
/* End the loop */
/* Return new string */
echo $mystring."<br/></br>";
}
}else{
/* Error Return start string*/
echo $mystring;	
}
}

findImage($string);

 

This is what the function returns:

Change this to an URL http://www.mytestsite.com/images/testimage.png And this one [[img:testimage1.png/Img]]

 

Now this is not right it should have done both of them, but i can not get it to do more then one.

 

Please can someone explain and help me to get it to do as many Img tags as there are.

 

Thanks for any help

in your while loop,

you should re-assign "$WhereImage_Start" and "$WhereImage_End"

to point to the second, (or third....) image..
