[SOLVED] Where to go?

[czukoman20]

Hi all, I am working on a project that uses checkboxes to select all or some of the 50 states.

I was wondering if there was an easy route to making them a variable that would be like.

 

F_FP_$state  and then that would show all the states they selected and nix all the states they didn't select.

 

Examples of what i have already.

<?php
<input type="checkbox"  name="AL[0]" id="list" value="AL" />
// That repeated 50 times with different state values.
// When the user submits the checkboxes
$AL =$_POST['AL']; foreach ($AL as $st_1){}
// That repeated as well for each state.
?>

<?php
<input type="checkbox" name="states[]" value="AL" />
// That repeated 50 times with different state values.
// When the user submits the checkboxes
$states = $_POST['states']; foreach ($states as $state){ echo $state; }
?>

Thanks, But for some reason when i did that.. it only echo's the last state that I selected.

<?php
<input type="checkbox"  name="states[0]" id="list" value="AL" />
<input type="checkbox" name="states[0]" id="list" value="HI" />
<input type="checkbox" name="states0]" id="list" value="MA" />
<input type="checkbox" name="states[0]" id="list" value="NM" />
// output
$states =$_POST['states']; foreach ($states as $state){ echo "$state"; }

// it echos NM when those 4 are selected?
?> 

 

also the twist to this is.. there are categories.. so each state needs its own Category Information

F_ = Financial

FP_ = Subcategory of Financial

So those need to be F_FP_$state But it needs to repeat itself like that for however many states are selected.. If they didn't select  a state I dont want the database to have a bunch of blank  "F_FP_  "

 

Thanks for the help so far

don't put a 0 in the square brackets. but using a 0, you are telling them to all use the same index of 0, with empty backets it will anonymously assign indexes

 

let's start with that before getting into the categories...if you get rid of the 0 does it work as you would expect?

[czukoman20]

Yes it does.

Now the output shows

ALHINAMH

thanks

 

Cool

Now for the categories... It wouldn't be as hard, but the page changes according to what the input in the url is..

Here is what i have so far

<?php
if ($cat1 == "FP_"){
$input = "F_FP_$state";
}
// of course that doesn't work lol 
?>
I'm thinking array, but idunno how to do that.

[rhodesa]

like this?

<?php
$states =$_POST['states'];
if ($cat1 == "FP_"){
  $input = array();
  foreach($states as $state){
    $input[] = "F_FP_$state";
  }
}
?>

SWEEET!!

Thanks a ton..

Just one final question.

The only way i know how to "echo" this is throught another foreach statement.

Also there is print_r();

Would I have to say

print_r($input[1,2,3,4,5,etc..]);

or is there a more simplified way?

 

Thanks for your help!!

[rhodesa]

how do you want to echo it? comma separated?

 

echo implode(',',$input);

[czukoman20]

interesting

the output is now

 

F_FP_AL F_FP_AL ,F_FP_HI F_FP_AL ,F_FP_HI ,F_FP_MA F_FP_AL ,F_FP_HI ,F_FP_MA ,F_FP_NM

 

Wierd, I bolded the States to make it easier to read

 

The code I am using is

 

<?php
<input type="checkbox"  name="states[]" id="list" value="AL" />
<input type="checkbox" name="states[]" id="list" value="HI" />
<input type="checkbox" name="states[]" id="list" value="MA" />
<input type="checkbox" name="states[]" id="list" value="NM" />

//output 

$states =$_POST['states'];
if ($cat1 == "FP_"){
  $input = array();
  foreach($states as $state){
    $input[] = "F_FP_$state ";
echo implode(',',$input);
  }
}
?>

Nevermind I figured it out... I had to put it on the outside of the Brackets... Ok
