Option Selected from PHP generated dropdown

[EVENT_HORIZON]

I'm just attempting to learn how PHP handles things and I can't quite wrap my head around how to apply Selected to the final Option and show the Traits for the Character based on the Selected Option.

 

I understand this might need POST, if it does, I would appreciate a bit of help on how I would set this up as POST since I didn't think a drop down required a submit button.

 

$character= array (array(Name=>"Barry","Class"=>"Fighter",Level=>1,Str=>10,Dex=>10,"Int"=>10),array(Name=>"Lindehar","Class"=>"Ranger",Level=>1,Str=>10,Dex=>10,"Int"=>10),array(Name=>"Verelden","Class"=>"Mage",Level=>1,Str=>10,Dex=>10,"Int"=>10));

print "Select a Character:<br /><select>";
foreach($character as $array_num)
{
foreach($array_num as $char_trait=>$trait_value)
{
	if($char_trait==Name)
	{
		$selected_value="";
		$generated_chars="<option selected=".$selected_value." value='".$char_trait."'>".$char_trait.": ".$trait_value."</option>";
		print $generated_chars;
			if($selected_value=/".$char_trait.": Barry"/")
			{
				foreach($char_trait=="Barry")
				{
				print "<h4>".$char_trait.": ".$trait_value."</h4>";
				}
			}
	}


}
}
print "</select><p />";

The <select> field needs a name attribute, and how are you planning to send a value anywhere if it isn't submitted somehow?

I understand it needs to be submitted but I thought that you could just add  POST to the dropdown, is this not correct?

Not so much, no. If you're looking to update the page based on the <select> field changing, without actually having to submit and reload the page, you would need to look into an AJAX solution.

if you want to do it with pure php ( and little bit of javascript. not ajax )

 

just submit the form to the same page , on the onchange method of the select, using javascript,

 

then capture the values on the top and do what you want to do

 

<select name="select_name" onChange="document.form_name.submit();">
