Hello all, and thanks for looking.
I'm trying to have a form, when filled out, will display a user custom profile fields from a vBulletin database. Now I'm not very good at programming at PHP, although I can figure out most of the small things. So knowing this, I tried to take a script I found somewhere on the internet and modify it to my needs. I was able to change it so it displays one of the custom profile fields, however I'm not sure how to set it to display more than one. The full code is below:
<?php
error_reporting(7);
require("./global.php");
function measure_string($s,$font,$fh,$ta)
{
// error_log("measure_string: font ." . $font . ".", 0);
list($blx,$bly,$brx,$bry,$trx,$try,$tlx,$tly) = imagettfbbox($fh,$ta,$font,$s);
return max($trx,$brx) - min($tlx,$blx);
}
function measure_char($c,$font,$fh,$ta=0)
{
$s1 = "mm";
$m1 = measure_string($s1,$font,$fh,$ta);
$m2 = measure_string("m" . $c . "m",$font,$fh,$ta);
return $m2 - $m1;
}
/*
* Given a string of text, return an array of lines
* wrapped to fit within line_width

{
$text_angle = 0;
$a_chars = array();
$linelen = 0;
$line_start = 0;
$lastpos = 0;
$line = "";
$len = strlen($text);
for ($i = 0; $i < $len; $i++) {
if (ctype_space($text[$i]) || ($text[$i] == "\n") || ($i == $len -1)) { // end of a word?
if (measure_string($line, $font,$fontheight, $text_angle) >= $line_width) { // backup
if ($lastpos > $line_start) {
$text[$lastpos] = "\n";
$line_start = $lastpos;
$line = substr($text,$lastpos+1, $i - $lastpos); // what if this $line is too long?
} else {
// handle case of no word breaks in line > width
// options: punt or insert newline
// choice: punt
// this code isn't right. maybe the right thing is to just insert a newline _here_.
while (($text[$i] != '\n') && !ctype_space($text[$i]) && ($i < $len)) {
$i++;
$line_start = $lastpos;
$line = "";
}
} // end if-else lastpos > line_start

}
}

The code I'm working on is the following:
global $vbulletin;
if ($vbulletin->userinfo['userid']!=0) {
$text=$vbulletin->db->query_first("SELECT field15,field90,field91 FROM userfield WHERE userid='$userid'");
$text=$vbulletin->userinfo['field15'];
} else {
$text='You need to Login or Register';
}
It displays field15 fine, but how would I go about setting it to show the other two if they are filled in? I've been trying for over a week to get it to do so, and I can't figure it out.
And also, would it be possible to set up a background image from a group of images?
Thanks again.
