Multiple selection in a form

ph3n0m

I have a form being generated from returned results from a basic db query.

The problem I am having is when people are using the generated form - how to track what selection they have made.

Example (output of partial form)

<input type=\"text\" size=\"2\" maxlength=\"3\" name=\"purchase[][qty]\" value=\"0\">
<input type=\"hidden\" name=\"purchase[][price]\" value=\"4.00\">

Each item has six options (so imagine the above repeated six times for each item (total number of items can be determined, but there is no minimum or maximum)

Anyway I have tried passing the above to another page (just to generate information) and I get nothing.

The code I am passing it to is

			foreach ($purchase as $key => $price){
			if($purchase[$key][qty] > "0"){
			// whats nice is that you will have
			// your values in the below hash
			// and you can do you db stuff
			echo $purchase[$key][price];
			}
}

Can someone point out what I am doing wrong or where I have screwed up - this is the last piece in a very long project for me

You'd probably get more reliable results if you used explicit array keys in the form name (purchase[0][price], purchase[1][price], purchase[2][price], and so on); then there'd be no argument about where the field data is supposed to be.

(Oh, and you are using $purchase = $POST['purchase'], aren't you? If you're not using $POST, you should be.)

(Oh again; why are you including the price in the form? If that's what it looks like you do realise that there is nothing stopping anyone from changing the price to anything they like in their submission.)

I set up the form to use explicit array keys as suggested, but I still cant get the subsequent page to display any thing apart from the reference

sample explicit key

<tr><td><img src="images/icon_recommend.gif" width="12" height="12" alt="" border="0"></td><td>4x6</td><td>

<input type="text" size="2" maxlength="3" name="purchase[0][qty]" value="0">
</td></tr>
<tr><td><img src="images/icon_notrecommend.gif" width="12" height="12" alt="" border="0"></td><td>5x7</td><td>
<input type="text" size="2" maxlength="3" name="purchase[0][qty]" value="0">
</td></tr>
<tr><td><img src="images/icon_notrecommend.gif" width="12" height="12" alt="" border="0"></td><td>8x10</td><td>
<input type="text" size="2" maxlength="3" name="purchase[0][qty]" value="0">
</td></tr>
<tr><td><img src="images/icon_notrecommend.gif" width="12" height="12" alt="" border="0"></td><td>16x20</td><td>
<input type="text" size="2" maxlength="3" name="purchase[0][qty]" value="0">
</td></tr>
<tr><td><img src="images/icon_notrecommend.gif" width="12" height="12" alt="" border="0"></td><td>20x30</td><td>
<input type="text" size="2" maxlength="3" name="purchase[0][qty]" value="0">
</td></tr>

			foreach ($image_ref as $key => $value){
				echo $value. "<br>
				";
					foreach ($purchase[qty] as $value){
					echo "<b>" . $value . "</b> | ";
					} 
				echo "<br>";
			}

What am I doing wrong with the above? basically I am just trying to display the image ref (which is held as an array and is displaying correctly) and also any qty entries for that specific image

Well, you have at least one problem with that new script. First, they all have the exact same name, so you will only get one value returned. I'm not really sure what you are going for, but chances are you want either this:

<tr><td><img src="images/icon_recommend.gif" width="12" height="12" alt="" border="0"></td><td>4x6</td><td>

<input type="text" size="2" maxlength="3" name="purchase[0][qty]" value="0">
</td></tr>
<tr><td><img src="images/icon_notrecommend.gif" width="12" height="12" alt="" border="0"></td><td>5x7</td><td>
<input type="text" size="2" maxlength="3" name="purchase[1][qty]" value="0">
</td></tr>
<tr><td><img src="images/icon_notrecommend.gif" width="12" height="12" alt="" border="0"></td><td>8x10</td><td>
<input type="text" size="2" maxlength="3" name="purchase[2][qty]" value="0">
</td></tr>

in which case you would go through it all like this:

foreach ($purchase as $value){
echo "<b>" . $value[qty] . "</b> | ";
}

or this:

<tr><td><img src="images/icon_recommend.gif" width="12" height="12" alt="" border="0"></td><td>4x6</td><td>

<input type="text" size="2" maxlength="3" name="purchase[0][qty][]" value="0">
</td></tr>
<tr><td><img src="images/icon_notrecommend.gif" width="12" height="12" alt="" border="0"></td><td>5x7</td><td>
<input type="text" size="2" maxlength="3" name="purchase[0][qty][]" value="0">
</td></tr>
<tr><td><img src="images/icon_notrecommend.gif" width="12" height="12" alt="" border="0"></td><td>8x10</td><td>
<input type="text" size="2" maxlength="3" name="purchase[0][qty][]" value="0">
</td></tr>

which would go like this:

foreach ($purchase[0][qty] as $value){
echo "<b>" . $value . "</b> | ";
}

I have no idea what your first for loop is for, and please bear in mind that (as they are listed) they both use the same variable, $value. I don't know if it's because it doesn't matter, you didn't notice, or just because those are example names, but I thought I would point it out anyway.
