HTML as PHP

@Kyleva2204Jan 30.2005

Hey all,

Got a question.. is there anyway you can have a HTML code that you created ie: <blah>… and have PHP grab it and replace it with something.. Now I know thats possible.. however is it possible for something like <show select=list> and have PHP pick up on the HTML <show>.. Then notice select is present and select LIST from a mysql table? I would like for this to be universal and PHP to know what its doing, otherthan coding LIST into the PHP. So I want the PHP to automatically detect LIST… Much Appreciated! ?

<_<... My ass.. The whole point of this is to make a CMS... Is there any possible way to do what im asking, besides some third party PHP app..????

@ShrineDesignsJan 30.2005 — #i would recommend using the template system from phpbb, it uses comments to dictate output

block var example

&lt;!-- BEGIN (this.that) --&gt;
 {this.that.name}&lt;br /&gt;
 {this.that.desc}
 &lt;!-- END (this.that) --&gt;

var example{MY_VAR}

um... alright whatever.. screw this topic.. No Offense, but I was just looking for some pregreplace that could detect vars inside of a HTML code.. :-!.. NVM it thou.. Ill figure it out sooner or later...

@ShrineDesignsJan 30.2005 — #preg_replace("/<show>(.+)</show>/i", "<b>1</b>", $html_page);

[B]preg_replace("/<show>(.+)</show>/i", "<b>1</b>", $html_page); [/B][/QUOTE] alright, now were getting somewhere.. I want the Pregreplace to find <show what=fields> and look up the contents of 'what' and then grab a MySQL table depending on 'what' is equal to... ok? LOL

@ShrineDesignsJan 30.2005 — #try

[code=php]<?php
 if(preg_match("/<shows+(\w)\s*\=\s*[\"\\']?(\w)[\"\\']?>(.+)</show>/i" $html_page, $matches))
 {
 $field = $matches[0][1];
 $value = $matches[0][2];
 $result = mysql_query("SELECT * FROM table WHERE $field = '$value'");
 $row = mysql_fetch_array($result, 2);
 $row = implode("<br />n", $row);
 preg_replace("/" . $matches[0][3] . "/i", $row, $html_page);
 }
 ?>[/code]

[/B][/QUOTE] alright man, im extreemly confused on the preg_match.. does a * represent anything? Like wildcard? yeah guess so.. ok but whats with all the backslashes.. and random letters!?!? ><... BTW.. im kinda a newbie.. learning as I go..

@Kyleva2204authorJan 30.2005 — #it wont work ?

@ShrineDesignsJan 30.2005 — #see: [url=http://www.php.net/manual/en/reference.pcre.pattern.syntax.php]PCRE regex syntax[/url]

try

[code=php]<?php
 $txt = "<show color="pink">adafdf</show>";
 
 if(preg_match("/<shows\s*color\=[\"\\']?([a-z0-9\#]+)[\"\\']?>(.+)</show>/i", $txt, $matches))
 {
 $txt = preg_replace("/show/i", "font", $txt);
 $txt = str_replace($matches[0][1], "adfad", $txt);
 }
 echo $html_page;
 ?>[/code]

@Kyleva2204authorJan 30.2005 — #a;right, that didnt work... lets simplify this for me and you.. How can you grab a wildcard in a string and set it as a variable in PHP.. haha, i think that is exactly what I am trying to do..

@ShrineDesignsJan 30.2005 — #there is no one wildcard in regexp, but the closes one would be: [b].[/b]

see for assigning variables:

and/or

@Kyleva2204authorJan 31.2005 — #ok, I went to the URLS.. I know how to set a varible.. But i want a part of a string.. like <blah dfadf=sdfads>.. I want the PHP to pick up dfadf and set a variable to the contents of dfadf.. understnad?
