Hello all!
I just noticed that there are no string output options in the Template Parser Class.
So I tinkered the class and found a solution.
In anyway I want to capitalize, lowercase, format numbers, etc. I just add an extra option in the view file of any variable you want to output.
Normally, in the Parser Class, we would do this in the view file:
Code:
<ul>
{blog_list}
<li>{title} - {content}...</li>
{/blog_list}
</ul>
But now, I can do this:
Code:
<ul>
{blog_list}
<li>{title:allcaps} - {content:climit:100}...</li>
{/blog_list}
</ul>
That way, I can capitalize the title and limit the content to 100 characters without modifying it in the controller.
There are several string output modifiers you can choose from, most of these came from CI's own helpers. You can also add your own custom modifier, just add a case option in switch menu.
So here is it, just copy the entire code and save as 'MY_Parser.php' in 'system\application\libraries' and edit your autoload.php add the necessary helpsers
system\application\config\autoload.php
Code:
$autoload['helper'] = array('url', 'string', 'text', 'security');
system\application\libraries\MY_Parser.php
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Parser extends CI_Parser {
function My_Parser()
{
}
function _parse_single($key, $val, $string)
{
$newval = $val;
$find = "/".$this->l_delim."".$key.".*".$this->r_delim."/U";
preg_match($find, $string, $matches);
if(!empty($matches))
{
$temp = trim($matches[0], "{}");
$res = explode(":", $temp);
if(count($res) > 1)
{
switch($res[1])
{
case "allcaps" :
$newval = strtoupper($val);
break;
case "money" :
$newval = number_format((int)$val, 2, ".", ",");
break;
case "caps" :
$newval = ucwords(strtolower($val));
break;
case "nocaps" :
$newval = strtolower($val);
break;
case "ucfirst" :
$newval = ucfirst($val);
break;
case "bool1" :
$newval = ($val==1) ? "True" : "False";
break;
case "bool2" :
$newval = ($val==1) ? "Yes" : "No";
break;
case "bool3" :
$newval = ($val==1) ? "Active" : "Inactive";
break;
case "climit" :
$int = (count($res)<3) ? 128 : $res[2];
$newval = character_limiter($val, $int);
break;
case "htmlchars" :
$newval = quotes_to_entities($val);
break;
case "wlimit" :
$int = (count($res)<3) ? 25 : $res[2];
$newval = word_limiter($val, $int);
break;
case "wrap" :
$int = (count($res)<3) ? 76 : $res[2];
$newval = word_wrap($val, $int);
break;
case "hilite" :
$str = (count($res)<3) ? "" : $res[2];
$color = (count($res)<4) ? "#990000" : $res[3];
$newval = highlight_phrase($val, $str, "<span style=\"color:{$color}\">", "</span>");
break;
case "safe_mailto" :
$alt_text = (count($res)<3) ? "" : $res[2];
$newval = safe_mailto($val, $alt_text);
break;
case "url_title" :
$sep = (count($res)<3) ? "dash" : $res[2];
$newval = url_title($val, $sep);
break;
case "remove_img" :
$newval = strip_image_tags($val);
break;
case "hash" :
$hash = (count($res)<3) ? "md5" : $res[2];
$newval = dohash($val, $hash);
break;
case "stripslashes" :
$newval = stripslashes($val);
break;
case "strip_tags" :
$allowed = (count($res)<3) ? "" : $res[2];
$newval = strip_tags($val, $allowed);
break;
/** other output string format options here **/
}
return str_replace($matches[0], $newval, $string);
}
}
return parent::_parse_single($key, $val, $string);
}
}
Some examples in your view:
Code:
<table>
<tr>
<td>Item: {item_name:ucwords)</td>
<td>Price: {price:money}</td>
<td>Description: {description:wlimit:20}</td>
<td>Email: {email:safe_mailto:Email Contact}</td>
<td>Avaliable: {status:bool2}</td>
</tr>
</table>
You can add your own format options there..
I just thought I'd share.. Thanks..
P.S.
It will still work if you don't put any output options.
