Template Parser Help.

Read Below.

[john tindell]

Right just to clarify you want to add if statements to you parser? What does your template look like?

[PlaGuE]

no. i dont want ot add an if statement to my parser.
What im tryingto do is "loop" an arry. with the assign_block_vars("blockname", $tag_array());

so taht

in between blocks like

<!-- START blocname -->
{blockname.tag}
<!-- END blockname -->

The template will ONLY hold the design.

if you thought i was assing an IF statement because of,

so if user isnt logged in {MembersTable.Email} == "Logged"
ELSE {MembersTable.Email} == user@domain.tld 

then im sorry if i gave the wrong idea.

the assign_block_vars should turn into an array and list many rows.But because of the fact that its returning Undefinded Offset 0 on the get_block and assign block vars. I've had to kee it static. So i have it only returns one row until i can fix it.

The errors occur in these to functions.

  function get_block($block){
    preg_match ('#<!-- START '. $block . ' -->([^.]+)<!-- END '. $block . ' -->#',$this->page,$this->return);
    $code = str_replace ('<!-- START '. $block . ' -->', "", $this->return[0]); //ERROR HERE
    $code = str_replace ('<!-- END '  . $block . ' -->', "", $code);
    return $code;
    } 

AND

function assign_block_vars($blockname, $data)
{
    $blockCode = $this->get_block($blockname);
    foreach ($data as $key => $value) {
        $blockCode = str_replace ("{".$blockname.".".$key."}", $value, $blockCode);
    }
    $this->page = str_replace ($blockCode.$this->return[0], $this->return[0], $this->page);//Error Here
}

Bumping it cuz i still cant figure it out... if you need me to clarify it more on what i am tryign to accomplish.. just say so.

[PlaGuE]

Bump T_t Cry

[penagate]

Can you try and really simplify this down to the concept of what you want to do? Because I really don't have a clue.

[PlaGuE]

Well Sure.

I am trying to loop content blocks.

the errors i get are from two functions... get_block and assign_block_vars

The errors are:

Notice: Undefined offset: 0 in C:\Program Files\Apache Group\Apache2\htdocs\cdstplcls\lib\parser.php on line 111

Notice: Undefined offset: 0 in C:\Program Files\Apache Group\Apache2\htdocs\cdstplcls\lib\parser.php on line 137

Notice: Undefined offset: 0 in C:\Program Files\Apache Group\Apache2\htdocs\cdstplcls\lib\parser.php on line 137

Notice: Undefined offset: 0 in C:\Program Files\Apache Group\Apache2\htdocs\cdstplcls\lib\parser.php on line 111

Notice: Undefined offset: 0 in C:\Program Files\Apache Group\Apache2\htdocs\cdstplcls\lib\parser.php on line 137

Notice: Undefined offset: 0 in C:\Program Files\Apache Group\Apache2\htdocs\cdstplcls\lib\parser.php on line 137

It repeats the lines two times because i have two entries.
If i had one entry. The Errors would only show once.

My goal is quite simple.


Here's a sample of how the file with the replace variables.
Not exactly as above.. but easiest to use for an example of wanted outcome.

<?php
include "parser.php";

$template = new Page("template.tpl");

$sql = "SELECT * FROM members";
$result = mysql_query($sql) or die('Could Not Do a SELECT Query for MEMBERS.');

while ($row = mysql_fetch_array($result)):

$template->assign_block_vars("Members", array("IP" => ($_SESSION['user_id'] != $row['id'] ? $row['ip']:'logged'),
                             "UserName" => $row['username']));

endwhile;
$template->output();

?>

And using this as my template file.

<!-- START Members -->
USERNAME :: {Members.UserName} IP :: {Members.IP}
<!-- END Members --> 

which would output
if logged in:
USERNAME :: PlaGuE IP :: 68.150.14.124

if not logged in:
USERNAME :: PlaGuE IP :: Logged


Hopefully with that example you get the picture.

Again I apperciate ANY help. As this problem is a big one for me...But you could probably see that already as i have been bumping this topic.

if you need more information just ask.

[penagate]

I am still really confused. All that code is going over my head.

If we go with this example

<!-- START Members -->
USERNAME :: {Members.UserName} IP :: {Members.IP}
<!-- END Members --> 

What problem are you having processing that?

Explain, don't hit me with mountains of code. I'm tired

[PlaGuE]

Okay, well if you were to test out the whole script/parser. you'de see it.

Here's an example of the script.

http://plague.chaoticdesignz.net/cdstplcls/

Btw sorry if all the codes going over yer head.

I just posted the complete parser file. the template file in which its being used. An example of how its being used....


also

I am trying to loop content blocks.

the errors i get are from two functions... get_block and assign_block_vars

This quote here is from a post above. What its saying is that the errors occur in both the get_block() and assign_block_vars() functions. HOWEVER it is really only erroring within the assign_block_vars() function due to it not "looping" the content. What its supposed to do is quite simple. However right now i cannot explain it due to the fact that, well idk how to explain it without getting you more confused aswell as confusing myself in the process.

The main problem is... its not looping. its just giving an error. because its not looping the variables. Once {Members.IP} becomes 68.xx.xxx.xx it stays that way. Which it shouldnt.it should go back to {Members.IP}

Hopefully that'll help.... since thats all i could muster outa me wee brain.

Again if you need more explaination. I'd be happy to. Seeing as how this has still eluded me.

I'd suggest testing out the provided code and looking at the errors.

[PlaGuE]

UPDATE: Beautified my parser script to look nice. So Now VisualAd and Pengate. YELP ME.lol...btw bump.
PS. I only bump after a certain ammount of time has passed

[PlaGuE]

Ohh my its zee bumpinator.

[penagate]

Enough. No more bumps.
