Creating an array from multiple text boxes

jasonb

I am having trouble creating an array of data collected from about 15-31 textboxes.

I create the textboxes using a for loop and specify 31 text boxes, and give them the name work$y.

How can I get that data into an array so that I can serialize the array and store it in a text field inside a mySQL database?

Another question: How can I test which was the last box to be filled in, for eg. box 15 or box 20, so that my array has the correct amount of elements.

Any suggestions will be useful.

Thanks
Jason

well if you have a checkbox that looked like this

You would have access to the array variable $work, and could access all the elements using a foreach loop. And for coding examples, if all three were checked, and you wanted to access them individually, you'd use

$POST['work']['0']
$POST['work']['1']
$_POST['work']['2']

and if only 2 were checked, you would use

$POST['work']['0']
$POST['work']['1']

the foreach loop is definately the way to go, but hopefully the examples cleared up any confusion.

BTW, if you're using a forloop, does it look like this:

for($y=0; $y<count($some_array); $i++) {
   echo "<input type='checkbox' name='work[" . $y . "]' value='" . $some_var . "'>";
}

If so, by giving it a name such as work['0'] and work ['1'] as the for loop goes on, then you'd have a 3 dimensional array that would need to be accessed using

$_POST['work']['0']['0']

(i believe)

Hi Cgraz

Thanks very much for your reply. It is very useful.

I managed to trudge through it and realised i can create an array from the word go.

My for loop looks as such:

for ( $y = 1; $y < 32; $y++ )
{
print "<tr><td align=\"right\">$y</td><td align=\"center\">";
--$y;
print "<input type=\"text\" name=\"work[$y]\"</td></tr>";
++$y;
}

Don't laugh!!! hehehe
I am fiddling around really, as I am on a steep learning curve and have quite a hooge project in mind.

Perhaps you could take a look at my code so far and perhaps if you have time can point me in the right direction???

Thanks again
Jason

could you explain what you want the code to do, and what the code you currently have is doing?
