combobox and some other help...

22896

Hello everyone.
I'm a starter in PHP, and hungarian. (My english needs some work)

so.. to get to the point,
i have a .php file wich pulls data from an .xml file.
(I can't belive, but I did manage to make it work HUH..)

The next problem what I face is, I need to create a combobox, the contents are needed to be pulled from an other .xml file.

so something like:

<option>$xml->dunnowhat->somestring</option>
<option>$xml->dunnowhat->otherstring</option>
<option>$xml->dunnowhat->someotherstring</option>

I found out that this would be html code, and would not know about variables I made in php.

Does php have a function to create dynamic content comboboxes?

(well... all this is made becouse me and some friends used to play with an old table game, but they moved so I try to make a port of it, so we can continue playing... And also at least I learn how to code php)

Well, thats all for now. From time to time when I realy get stuck I will ask here, if it is o.k. Seems like this project is bigger than my brain 🙂

Your English is much better than my Hungarian. 🙂

I am not sure what the exact solution will be for you since I do not know the details of how the data is organized. But presumably there is some sort of array of data that you want in your options list. You could therefore use the [man]foreach[/man] loop to iterate through each value. As a general example, it might look something like:

<select name="example">
<?php
foreach($xml->top_element as $value)
{
   echo "<option value='{$value['item_id']}'>{$value['item_name']}</option>\n";
}
?>
</select>

Wow, thats a fast reply!
Many thanks.
I will try that 🙂

Structurizeing the code so far is a bit not easy, since even I don't know whats the final structure might look like 🙂

Loking at that code, may I think that.. if I load an .xml file into an array,
the .xml file can contain something like:
<thing>
<specimen>a</specimen>
<specimen>b</soecimen>
</thing>

so no problem that <specimen> exsist on the same level more than ones times.
But then comesthe question, how are they identified?

mmm.. only a few hours messing with php, and I also have to mess with database, LOL...

If you are using PHP5, then you can use the [man]simpleXML[/man] functions, e.g.:

<?php
// sample XML data:
$xmlString = "<?xml version='1.0' encoding='UTF-8' ?>
<thing>
<specimen>a</specimen>
<specimen>b</specimen>
</thing>";
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html lang='en'>
<head>
<meta http-equiv='Content-Type' content='text/html; charset=UTF-8'>
<title>Test</title>
</head>
<body>
<form action='<?php echo $_SERVER['PHP_SELF']; ?>' method='post'>
<fieldset style='width: 9em'>
<legend>XML Test</legend>
<select name='specimen'>
<?php
// load XML data into simpleXML object:
$xml = simplexml_load_string($xmlString);
// loop through each 'specimen':
foreach($xml->specimen as $specimen)
{
   echo "<option>$specimen</option>\n";
}
?>
</select>
<input type='submit' value='Submit'>
</fieldset>
</form>
<?php
// Show the results:
if(isset($_POST['specimen']))
{
   echo "<p>You selected: " . $_POST['specimen'] . "</p>\n";
}
?>
</body>
</html>

If the XML data is in a file, then you would use the [man]simplexml_load_file/man function instead of [man]simplexml_load_string/man.

Aha, thats a verry useful post, things are getting clear.
Thank You for Your time 🙂

My .xml basefile need some editing,and it will work like a charm.

Well, its 2:40 in the morning now, and someone has to work from 7:00 🙂

When I get my self in shape again I will edit my xml to fit a nice buildup that can be feed in comboboxes .
