PHP: What will a SELECT with multiple selected values give?

[iceangel89]

What will a <SELECT> with multiple selected values give? for example:

<SELECT>
<OPTION>Option 1</OPTION>
<OPTION>Option 2</OPTION>
<OPTION>Option 3</OPTION>
<SELECT>

Then i select Options 1 & 3, then what will the POST or GET output be like? i have no problems with 1 selected but if more that 1 is selected i think i will get an array?

It will return whatever the value of the selected objects are :)

So, if you have:


<select name=MyAwesomeSelections multiple>
<option value="number01">Number 1 Is The Best</option>
<option value="number02">I Disagree, Number 2 Is The Best</option>
<option value="number03">On Third Thought, Number 3 Rocks</option>
</select>


And someone selects the first and the third options, then it will return "MyAwesomeSelections = number 01, number 03". Does that help?

[iceangel89]

That means if the variable is $_POST['MyAwesomeSelections'], the string will be "number 01, number 03"? and if its GET, it will be filename.php?MyAwesomeSelections=number 01,number 03?

sorry abit noob here

What my lecturer did was name the SELECT "something[]" as an array, then the variable was $_POST['something']. then used a fornext loop to extract selected values, didn't quite understand that and it didn't work for me.

You got the first part right.

Also MyAwesomeSelections in the above example is automatically converted into an array (i'm pretty sure)

Now, i've never heard of a fornext loop and a quick google search wasn't very promising. I think you mean a foreach loop. What that loop does is:

foreach ($w in $MyAwesomeSelection)
{
}

that assigns the fist value of the array to $w, so you can do what you want like print it or something, then when it loops back, it goes to the next entry in $MyAwesomeSelection and sets it to $w and so on...

Since this is a for you will want to stick with the POST method, but yes, both methods save the 'value' attribute, so make sure its something meaningful.

I thought I would just put you a file together so you can see the whole thing working. It's the same methods laxman pointed out.
