Need PHP help

hello…

i sorta follow how you have your code but without seeing it i can’t say for sure (the generated html didn’t help much, unfortunately)…but there are 2 basic ways to do a tally in a loop.

——————
example 1
——————

you have an array of elements like this:

$foo = array(“apple”, “orange”, “strawberry”);

and you want to have your pulldown increment situation – so you could do either of these:

$tally = 1;
foreach ($foo as $f) {
    echo “<OPTION VALUE=\”{$f}_{$tally}\”>{$f}</OPTION>”;
    tally++;
}

or

for ($i=0; $i < count($foo); $i++) {
    echo "<OPTION VALUE=\"{$foo[$i]}_".($i + 1)."\">{$foo[$i]}</OPTION>”;
} 

(btw – the { } chars around the variable in the echo are just to help php and the code reader see the full variable name – they border the variable. it can also sometimes be needed if you want to keep the quote string going, as if (for example) you have a variable called “$bar” – if you reference it in a quoted string as “$bar_text”, php will think the var name is “bar_text” – but if you do “{$bar}_text”, then it will see the correct var name)

——————
example 2
——————

you have a hash/associative/key value array of elements like this:

$foo = array(“fruitApple”=>”Apple”, “fruitOrange”=>”Orange”, “fruitStrawberry”=>”Strawberry”);

then you can make use of the key value like this (very similar to the first example above):

$tally = 1;
foreach ($foo as $k=>$v) {
    echo “<OPTION VALUE=\”{$k}_{$tally}\”>{$v}</OPTION>”;
    tally++;
}

does that do what you need?

should be $tally++; (with the dollar sign)….

I can’t tell you how much I appreciate your time and knowledge!

I think I’m closer, but still not getting something.

I’ve zipped up the code so you can see it:
Here’s the code!

So here’s my thinking using the variables in place in this script…

The page creates $imnum number of images, each with pulldowns to select quantities of 5×7, 8×10, 10×15 and 15×18 sized prints.

I would like the returned value for the first image’s (image 1) 5×7 quantity to be a variable called $5x7_1, the second image’s to be called $5x7_2, etc.

Currently, I’m using a for loop with the $rowmaker variable controlling the loop. This $rowmaker variable can also be used to tack on the appropriate _1, _2, etc end to the print size variables, but I can’t get the script to read it as $5x7_1 when I use $5x7_$rowmaker. I think I tried using the {} in all combinations, but it still won’t work.

Ideally, the script would just use $_POST[‘5x7_$rowmaker’] to read these values, but I don’t even know if you can get it to read a variable in the $_POST context.

I’m trying to make the page values sticky – when the user updates the cart, the page reloads. It isn’t until they checkout that they move on to a new page.

Again – thank you so much for taking any time at all with this!

hello…

ok – took a look and i think i see what you want – also based on what you said here – using a $_POST[‘5x7_$rowmaker’] variable would be the way to go…so something like this:

echo “<SELECT NAME=\”q5x7_{$rowmaker}\”>”;
for ($q=1; $q <= 10; $q++) {
    echo "<OPTION VALUE=\"$q\" ".(($_POST["q5x7_{$rowmaker}"] == $q) ? "SELECTED" : "")."\">$q</OPTION>”;
}
echo “</SELECT>”;

assuming your pre-select is the only issue? if not feel free to let me know – it’s early on a saturday here and i’m still waking up… 🙂
