php if elseif else

[facarroll]

I have a data form which sends to a mysql database.

In the database I have 6 fields which are informed by check boxes and that dataevaluates to true("1") or false("0").

I am trying to write a short script to check whether one or more boxes were checked. I am new at this, but what I've written works well. The problem I have is that I don't know how to insert the script so that it allows the original script to continue if one of or more of the fields evaluates as true.

This is what I have. There is something wrong at the end, I think.

Try something like:

 

// perform query
// assuming $data contains the row

$valid = false;

foreach ($data as $chkbox)
{
    if ($chkbox == true)
    {
        $valid = true;
        break;
    }
}

if ($valid)
{
    // do something here
}

Sorry Mr Adam, don't understand. I'll post my script here and see if you can figure out what I'm doing wrong.

I've posted the working script with the part I cannot get to work is commented out. (lines 54-68)

If I uncomment the lines the script stops.

Any help?

Sorry I think I misunderstood what you were asking before (thought you were asking to validate there was at least 1 check box ticked for an entry in the database).

 

Start again...

Right then rather than giving each check box a unique name, store them as an array:

 

<input type="checkbox" name="egroup[]" value="My check box" />

 

On the PHP side you can then spit out the error if the array is empty:

 

if (empty($_POST['egroup']))
{
    exit('You must select a group. No selection has been made');
}

 

The value for the check box is only posted if it's been checked.

Got it with this.

 

$nogroup = ((!$egroup1) && (!$egroup2) && (!$egroup3) && (!$egroup4) && (!$egroup5) && (!$egroup6));

$noequip = (!$equip);

if ($nogroup){

$errorMsg .= "--- Student Group. (No data was forwarded to the database.)</font>";

} else if($noequip){

$errorMsg .= "--- Quiz Name. (No data was forwarded to the database.)</font>";

} else {

 

 

Thanks for your help.
