Process form values via loop

Question

I have a form that has fields with the following name

<input type="text" name="value[]">
<input type="text" name="value[]">
<input type="text" name="value[]">

On form submit I need to run a query and store each submitted non-empty values into my db. How do I do that? I suppose I need to run loop but not sure how and especially to avoid blank field submissions.

i would first suggest do a print_r($_GET['value']) for get or print_r($_POST['value']) for post and see what prints out. — KJYe.Name

Oh, it submits fine, I can see all fields submitted and which ones have values or not. How do I integrate this in my code though? — santa

I don't have any yet. I was thinking something along the lines: for($i = 0; $i < sizeof($value); ++$i) { //db query } but this does not weed out blank submissions. Do I just run a loop and validate before db query is run? — santa

why not to add some condition inside of the loop? and make db query conditional (note that you don't have $value but $_POST['value']) — Your Common Sense

foreach($_POST['value'] as $val)
{
   if($val != "")
   {
       //process query, $val will have the tag's value
   }
}

Your Common Sense Over a year ago

checking for isset after assigning a variable makes no sense.

I was afraid of that. Edited to restrict empty values.

Can't I add TRIM and then check if ($val != '') or (!empty($val) ?

Your Common Sense Over a year ago

You're @santa. you can do anything at your wish, don't you? sure you can add trim, nobody forbids you that. empty() is redundant too.

@Col. Shrapnel actually the one I use mainly looks for script inserts. Fairly benign and quite fast. I'd rather strip someone's HTML rather than run a risk of having someone's code stored in my db. But this is a subject for a whole different discussion.
