View Full Version : How do I set variables?

Simple question, but elusive to me. How would I define a new variable to be used in a template.

Say I wanted to use $aaron and have a new bit that would display "Aaron is AwesomE!" wherever I put that in my templates.

In a similar vein, what if I wanted to use some PHP if/else to determine if a variable is set and if it is display it and if it is not, do not. An example of this would be in the postbit of my forum http://forums.livetheworship.com where I added $post[field7] (CD currently being played) to my postbit. I was trying to figure out how to test to see if a user set anything and if they did, display that variable and if they did not, then it would not display at all. Since I couldn't figure it out I had to settle on using (nothing) in my table for field7. Any ideas how to do these things.

In Summary:
1. how Do I add a new bit and then use it in the template system?
2. How do I set a variable in PHP and then use it in the templates?

Thanks.
Aaron

PS. If I can figure these simple things out, whole new worlds of mids will open up to me.

new bit code:

<?php

$bit = eval("all the template proccessing code, lookup form any file");

?>

ummm....not sure what you mean. Sorry. I know PHP and I understand eval() but I don't know how you're saying to work this....mind explaining a bit more? :) Thanks.

I am guessing you put the following after maybe if statement or something
eval("\$aaron = \"".gettemplate('aaron_template')."\";");
in aaron_tempalte it would have the Aaron is cool, and then whatever file you put that in, like index.php put $aaron in the template, and it will say Aaron is cool.

I am taking a shot in the dark here.

I'll try it again, but that's what I thought too and it didn't seem to work. I tried it with like something like $x = 1; without any kind of if/else statement....just plain hardcoded variable, and then did

eval("\$x = \"".gettemplate('postbit')."\";");
and put $x in the template and it didn't seem to do much of anything....nothing was displayed. That's why I'm so confused.

LOL....

This SUCKS!

Okay, This is what is in my showthread.php at the very end of the file:

//*********************Custom Field Hack********************
$tid = $thread[postuserid];
$customsql=mysql_query("SELECT * FROM userfield WHERE userid = '$tid'") or die(mysql_error());

while($custom=mysql_fetch_array($customsql)){

$field7 = $custom['field7'];

if($field7 == NULL)
{
$cdnow = "";
}
else
{
$cdnow = "<b>CD I am Playing:</b> <br>$field7";
}

eval("\$cdnow = \"".gettemplate('postbit')."\";");
}
//************************************************** ********
eval("dooutput(\"".gettemplate("showthread")."\");");
?>

And my postbit portion:

<b>$post[avatar]</b>
<normalfont><br>
<b>$post[username]</b>
</normalfont><br>
<smallfont>
$post[usertitle]<br>
$post[hasaward]
</smallfont><br><br>
<!---This was put here to see if $post[field7] would get to the page...it does
<smallfont>
<b>CD I am Playing:</b>
<br>$post[field7]</smallfont>
--->
<!---this should be what is displayed but it's not --->
$cdnow


So how do I get $cdnow to the screen???

I think this should be at the end of the file :

//*********************Custom Field Hack********************
$tid = $thread[postuserid];
$customsql=mysql_query("SELECT * FROM userfield WHERE userid = '$tid'") or die(mysql_error());

while($custom=mysql_fetch_array($customsql)){

if($post[field7] == "") {
$cdnow = "";
} else {
eval("\$cdnow = \"".gettemplate('postbit_cdnow')."\";");
}

//************************************************** ********
eval("dooutput(\"".gettemplate("showthread")."\");");
?>

Then...Create a template called : postbit_cdnow
Contents :
CD I am Playing:</b><br>$post[field7]

Then in the postbit template, add "$cdnow" where you want it...

yeah I actually changed that in my php al;ready. Still doesn't work. And in the postbit, I am using $cdnow. Notice the $post[field7] deal is in comments...

try using $post[cdnow] in your postbit. I doubt it matters, but :D

no that wouldn't and doesn't work. cdnow is not a field in the db so it wouldn't be a variable included in $post...
