[SOLVED] Not receiving data from array

Cep · December 21, 2006

Hello,

I am using a modified XML parser to read in some custom XML data. The script should then take this data and output it into an HTML file displayed on the users screen.

The problem I am having is that I am getting no record data at all, just a repeat of the template that the code should produce.

I know this must have something to do with my two for loops but I am unsure why, logically for each key in the first array $record there will be another array $arr as its value and then the second loop will loop through $arr to get the record information.

Here is my code,

[code=php:0]
<?php
$arr = array();
$record = array();
$flag = "";
$count = 0;

$pagestart= "<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Transitional//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'>
<head>
<title>Professional Development Courses Introductory</title>
<style type='text/css'>

</style>
</head>
<body>
<div align='center'>";

function opening_element($parser, $element) {

global $flag;
$flag = $element;

}

function character_data($parser, $data) {

global $flag;
global $arr;
global $count;
global $record;

switch($flag) {
case "record":
$count = 1;
break;
case "/record":
case "myData":
case "/myData":
case "":
break;
default:
$arr[$count] = $flag."~".$data;
$count++;

if ($count==13) {
$record[] = $arr;
$arr = array();
}
break;
}

}

function closing_element($parser, $element) {

global $flag;
$flag = "";

}

$parser = xml_parser_create();
xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, false);
xml_set_element_handler($parser, "opening_element", "closing_element");
xml_set_character_data_handler($parser, "character_data");

$document = file("default.xml");

foreach ($document as $line) {
xml_parse($parser, $line);
}

xml_parser_free($parser);

echo $pagestart;

foreach ($record as $arr) {

for ($z = 1; $z <= 12; $z++) {

$value = $arr[$z];

$from_date = "";
$title = "";
$start_time = "";
$speaker = "";
$group = "";
$v_address = "";
$objectives = "";
$content = "";
$attend = "";
$speaker = "";
$fees = "";

if($value!="~") {
//echo "line {$count}: {$value}<br />";
//$count++;

$split = explode("~", $value);

switch ($split[0]) {
case "from_date":
$from_date = $split[1];
break;
case "title":
$title = $split[1];
break;
case "start_time":
$start_time = $split[1];
break;
case "end_time":
$end_time = $split[1];
break;
case "speaker":
$speaker = $split[1];
break;
case "group":
$group = $split[1];
break;
case "v_address":
$venue = $split[1];
break;
case "objectives":
$objectives = $split[1];
break;
case "content":
$content = $split[1];
break;
case "attend":
$attend = $split[1];
break;
case "speaker":
$speaker = $split[1];
break;
case "fees":
$fees = $split[1];
break;
}

// Check content for hash breaks
$hashes = substr_count($content, "#");

if ($hashes > 0) {
$fragments = explode("#", $content);

for ($i = 0; $i <= $hashes; $i++) {

switch ($i) {
case 0:
$content = $fragments[$i]."<ul>";
break;
case $hashes:
$content .= "</ul>".$fragments[$i];
break;
default:
$content .= "<li>".$fragments[$i]."</li>";
break;
}
}
}
}

$row = "<table>
<tr>
<td>
<table border='1' align='center'>

<td>

<br />

echo $row;
}
}
$pageend = "</div></body></html>";

echo $pageend;
?>

And here is a sample of my XML.

[code]

Its ok I have spotted that the echo for pagemid is in the wrong loop and the variables for each record data are also on the wrong loop. Solved it!
