[pmwiki-devel] FW: $12.50 -> .50 var problem

[J. Meijer]

Jason is right.   $v = preg_replace('/\$[0-9]/', '\\\\$0', $v);Should work. $12 to him. To also protect against \\12.50in your data the best I can do is follows./jm<?php   # you need this while developing!error_reporting(E_ALL);  # init test vars$v='One $, $12.50 \\12.50 \\\\12.50 \1';    print $v;  $ff='something';$newpage['text']='text with (:something: value:) embedded';  # the essential bit $v=str_replace(array('\\','$'),array('\\\\','\$'),$v);if (strpos($newpage['text'], "(:$ff: ") !== false)  # not needed at all, complicates your code (Kathryn is your friend)  $newpage['text'] = preg_replace("/\\(:$ff: (.*?):\\)/s", "(:$ff: $v:)", $newpage['text'], 1);    print " <br/>\n$newpage[text]";  exit;From: commentgg at hotmail.comTo: editor at fast.st; pmwiki-devel at pmichaud.comSubject: RE: [pmwiki-devel] $12.50 -> .50 var problemDate: Tue, 10 Apr 2007 13:15:30 +0000






I'm now busy resolving your problem. Before starting there are a few problems with your code upfront:> if (strpos($newpage[text], "(:$ff: ") == true) $newpage['text'] =  preg_replace(>            '/\\(:'.$ff.': (.*?):\\)/s',  "(:$ff: $v:)",  $newpage['text'], 1);1. Do this in anything you are developing:     error_reporting(E_ALL);    # let PHP help you2. strpos returns either false or a number. Don't test for 'true', test for ' !== false ' (note this isn't ' !=false ' )strpos($newpage[text], "(:$ff: ") == true    3. Use quotes as in $newpage['text']  (point 1 would have helped you here). Now getting to the regex part. Seems like you have to preg_quote()/jm > > On 4/9/07,  The Editor  wrote:> The following is causing me huge problems.
