FUNCTION

Right let me show you the function... then explain whats wrong =]

PHP Code:

---

function replace($string)
{
 $pattern[0] = "{site_domain}";
 
 $replacement[0] = "$site_domain";
 
 ksort($pattern);
 ksort($replacement);
 eregi_replace("$pattern", "$replacement", "$string");
 return $string;
} 


---

It is designed such that, when I add other values, it will do the same for them... Right, in my database is {site_domain} and im trying to replace it to be $site_domain (a previously defined variable).

However, with and/or without the function, the end result for {site_domain} is %7bsite_domain%7d yet no where in the coding is it told to htmlspecialchars itself. And when trying to use the function but replace %7b to $, it still doesnt work -.-

Anyone got a function that will change the {x} to $x for any variable... that works =]

Moved by Agesilaus (Forum Moderator) from Design and Development: Please post in the correct forum.

Simple answer, there the {} ?

Secondly why the hell are you useing arrays anyway when you only have a single value?? or performing a direct string replace with the eregi command even? its kinda a waste or proccessing.

A correct and simpler version of your code could be done with a simple
function replace($string)
{
$string = str_replace("{site_domain}", $site_domain, $string);
return $string;
}

tho its kinda pointless as theres no reason for it to be a function if it is really only doing one task "/ (you may as well just use the str replace function itself in there)

Like i said.. it have more variables...
Ill be adding them as i go along, so indeed, the function is needed, its easier for when it comes to the CMS system.
Any idea on how to make it work?

Ok, though the ksort and use of the ergi instead of str replace still seems unnessary?

Oki, changed to preg_replace... however the function still wont work...
Any idea how to get it to work.. i think the problem is that its being htmlspecialchars without being told to... :S

No, its becuse your useing preg_replace instead of string... preg uses regex style patterns, which likely mans {} are read as parmiters for the replace string and in tern not replaced in the final document. why is it your so opposed to useing str_replace when replaceing strings?

I told you the code earlier..

Use entors and add more str_replaces for each thing u wish to replace?

ie

PHP Code:

---

function replace($string)
{
$string = str_replace("{site_domain}", $site_domain, $string);
$string = str_replace("{site_name}",$site_name,$string);
return $string;
} 


---

str replace should support arrays just as well as any other function?

PHP Code:

---

function replace($string)
{
 $pattern[0] = "{site_domain}";
 $pattern[1] = "{site_name}"; 
 
 $replacement[0] = "$site_domain";
 $replacement[1] = "$site_name"; 
 
 ksort($pattern);
 ksort($replacement);
 
 str_replace($pattern, $replacement, "$string");
 
 return $string;
} 


---

Still wont replace the {site_domain} with its value -.-

Why do you keep doing this? We have told you how to do it yet you refuse to listen.

Maybe if you listened to what we're trying to tell you it would.

I dont see the point in this thread if your ignoring everything we suggest.

No need to enclose the $string in quotation marks.

You actually havent suggested anything :S

Well maybe i was giving to much credit in assuming you knew how to correctly use a function as you appear to have ignored almost everything thats been said.. This example "Should" work.

PHP Code:

---

//Create all the vars
$information = "i like to eat {food} while drinking a glass of {drink}";
$myfood = "waffles";
$mydrink = "bleach";



function replace($string)
{
 $pattern[0] = "{food}";
 $pattern[1] = "{drink}"; 
 
 $replacement[0] = $myfood;
 $replacement[1] = $myfrink; 
 $string = str_replace($pattern, $replacement, $string);
 
 return $string;
}

$information = replace($information);
echo $information;
}

*correct me if wrong i aint done php in ages

Thats the function i had anyway....

Gets the info from the database... runs..

$templateHTML = replace($nav[templateHTML]);
echo "$templateHTML";

But still doesnt change it... i dont think the problem is with the function .. out of the function it works, put it in a function and it breaks????

You get $nav[templateHTML] how? Also you DO NOT need to inclose lone variables in quotation marks fgs. Just slows your script down.

I get it with the query...
The query works, because the template is echoed out, but it wont change the variables before it does...

fgs

PHP Code:

---

<?php

//Create all the vars
$information = "i like to eat {food} while drinking a glass of {drink} then shopping in {store}";


function replace($string)
{
    $myfood = "waffles";
    $mydrink = "bleach";
    $store = "Wal-Mart";

    $find = array("{food}", "{drink}", "{store}");
    $replace = array($myfood, $bleach, $store);
    $string = str_replace($find, $replace, $string);

    return $string;
}

$information = replace($information);
echo $information;


?>

---

Thats what i got...

PHP Code:

---

function replace($string)
{

 $pattern = array("{site_domain}", "{site_name}"); 

 $replacement = array("$site_domain", "$site_name"); 

 str_replace($pattern, $replacement, $string);

 return $string;
}

All variables are already defined.... but the function wont work... it physically does doesnt change it to anything. Your all saying the same thing, and im saying if you listen, its not working...

If $site_domain and $site_name are already defined in the script then you need to global them into the function:

PHP Code:

---

function replace($string) {
global $site_domain,$site_name;
....

not always, you could do:

PHP Code:

---

class hi
{
var $sitedomain;
var $site_name;
function replace($string)
{
whatever
}
} 


---

and then do

PHP Code:

---

$function = new hi;
$function->sitedomain = $sitedomain;
$function->site_name = $site_name;
$function->replace("hi"); 


---

although yours is easier.

I didn't think you had to global things in unless they were in a class?

Wow, learn something new every day =]

neither did i, and i just learnt what global did lol.

edit: btw, ive only seen global in a class before and didnt have a clue what it meant, so, ye.

If you do not global outside variables into the function then the newly defined variables within the function will be returned as null.

Example:

PHP Code:

---

$site='32';
function something($string) {
$string = $site.$string;
} 


---

The value of $site within the function would be blank / null.

so if you did global in a class you would be able to use the variables in all of the class' functions?

I believe you need to global it on each function.
