preg_replace

[drisate]

Hey guys i have a tag that looks like this

[CAL=02/2008]

 

i tried using

 

$content = preg_replace('/\[CAL(=([0-9]+/[0-9]))?\]/ie', "getJobs($2, 'CAL')", $content);

 

but it gives me this error

 

Warning: preg_replace() [function.preg-replace]: Unknown modifier '[' in /home/direct/public_html/administrator/components/com_acajoom/classes/class.jmail.php on line 160

maybe you need to escape the central /, e.g. \/ ? maybe it's treating that as end of statement

[DarkWater]

Yeah, you need to escape the \ in the middle:

 

$content = preg_replace('/\[CAL(=([0-9]+\/[0-9]))?\]/ie', "getJobs($2, 'CAL')", $content);

 

You may want to write another function other than getJobs() if you're going to be doing more things.  It's better than passing all those params in and stuff. >_<

hehe this is what i was planning to do

 

if (!function_exists('getJobs')) {
function getJobs($limit=NULL, $type) {

if ($type=="JOB"){$table="jos_jl_jobposting"; $col="title";}
if ($type=="SHOP"){$table="jos_marketplace_ads"; $col="ad_headline";}
if ($type=="CAL"){$table="jos_extcal_events"; $col="title"; $limit="10";} 

   $query = "SELECT * FROM $table";
   if ($limit != null) {
         $query .= " LIMIT $limit";
   }
  $res = mysql_query($query) or die(mysql_error());
  while ($row = mysql_fetch_assoc($res)) {
          $jobs[] = $row[$col];
  }
  return implode('<br />', $jobs);
}
}

$content = preg_replace('/\[JOB(=([0-9]+))?\]/ie', "getJobs($2, 'JOB')", $content);
$content = preg_replace('/\[sHOP(=([0-9]+))?\]/ie', "getJobs($2, 'SHOP')", $content);
$content = preg_replace('/\[CAL(=([0-9]+\/[0-9]))?\]/ie', "getJobs($2, 'CAL')", $content);

 

The first 2 works great but [CAL=2008/10]  is not recognized. the reason i added $limit="10"; to the CAL if type is because i did not create the SQL string to retrieve the data by date.

 

Anyway, looks like

 

$content = preg_replace('/\[CAL(=([0-9]+\/[0-9]))?\]/ie', "getJobs($2, 'CAL')", $content);

 

is not recognizing [CAL=2008/10].

[rarebit]

do you understand how the () brackets create numbered groups? It's ages since I need to use regex so I can't rem how they'll effect this...

[drisate]

Well i just tryed this

 

$content = preg_replace('/\[CAL(=([0-9]+)\/([0-9]))?\]/ie', "getJobs($2, 'CAL')", $content);

 

And it's not working either ... [CAL=2008/10]  stays unreplaced

 

The reason why i tryed it in the same () is because 2008/10 should be 1 value But i am not an expert on the question so i might be wrung ...

[rarebit]

$content = "[CAL=2008/10]";
$content = preg_replace('/(\[CAL\=([0-9]*)\/([0-9]*)\])/', 'XXX', $content);
print "content: ".$content."<br><br>";

or something like!

[drisate]

OMG ! thx rarebit i added ie to your string and it worked thank you so much bro!

If I am not mistaken, I think you need to use preg_replace_callback if you wish to create / call a function from within the replace aspect of preg. Granted, I have been known to be wrong (on more occasions than I care to admit).

Nah, you can use the e modifier to make the replace actually an eval'd portion of code.  I like it better for times where you may need to add things around the sides of the function output or do formatting or something.

Ah, just tried it. Nice to know

Will definitely come in handy to be sure.
