Problem with PHP script checking values

Hello everyone,

I'm trying to make a script that checks values, to see if a value is in use or not. If all the values are in use, it displays a message. If any of the values are not in use, it does not display a message.

Here is what I have created -

while($content = mysql_fetch_array($display25))
$content1 = $content['h1'];
$content2 = $content['h2'];
$content3 = $content['h3'];
$content4 = $content['h4'];
$content5 = $content['h5'];
$content6 = $content['h6'];
$content7 = $content['h7'];
$content8 = $content['h8'];
$content9 = $content['h9'];
$content10 = $content['h10'];
$content11 = $content['h11'];
$content12 = $content['h12'];
$content13 = $content['h13'];
$content14 = $content['h14'];
$content15 = $content['h15'];
$content16 = $content['h16'];
$content17 = $content['h17'];
$content18 = $content['h18'];
$content19 = $content['h19'];
$content20 = $content['h20'];
$content21 = $content['h21'];
$content22 = $content['h22'];
$content23 = $content['h23'];
$content24 = $content['h24'];

if ($content1=="BLANK")
{}
else
{
if ($content2=="BLANK")
{}
else
{
if ($content3=="BLANK")
{}
else
{
if ($content4=="BLANK")
{}
else
{
if ($content5=="BLANK")
{}
else
{
if ($content6=="BLANK")
{}
else
{
if ($content7=="BLANK")
{}
else
{
if ($content8=="BLANK")
{}
else
{
if ($content9=="BLANK")
{}
else
{
if ($content10=="BLANK")
{}
else
{
if ($content11=="BLANK")
{}
else
{
if ($content12=="BLANK")
{}
else
{
if ($content13=="BLANK")
{}
else
{
if ($content14=="BLANK")
{}
else
{
if ($content15=="BLANK")
{}
else
{
if ($content16=="BLANK")
{}
else
{
if ($content17=="BLANK")
{}
else
{
if ($content18=="BLANK")
{}
else
{
if ($content19=="BLANK")
{}
else
{
if ($content20=="BLANK")
{}
else
{
if ($content21=="BLANK")
{}
else
{
if ($content22=="BLANK")
{}
else
{
if ($content23=="BLANK")
{}
else
{
if ($content24=="BLANK")
{}
else
{ echo "There are currently no spots available for $result"; }}}}}}}}}}}}}}}}}}}}}}} }

PHP:

Now, if all the spots are "BLANK", it does not show the message (There are currently no spots available for $result). However, if even one of the spots is not blank, it shows the message.

I want it so that it only shows the message if all of the slots are not blank.

Thanks!

 

stick them all in the same if statement

if($content1=="BLANK" || $content2=="BLANK" || $content3=="BLANK" ...

Code (markup):

|| means "or" if you were wondering

 

I changed it to

while($content = mysql_fetch_array($display25))
$content1 = $content['h1'];
$content2 = $content['h2'];
$content3 = $content['h3'];
$content4 = $content['h4'];
$content5 = $content['h5'];
$content6 = $content['h6'];
$content7 = $content['h7'];
$content8 = $content['h8'];
$content9 = $content['h9'];
$content10 = $content['h10'];
$content11 = $content['h11'];
$content12 = $content['h12'];
$content13 = $content['h13'];
$content14 = $content['h14'];
$content15 = $content['h15'];
$content16 = $content['h16'];
$content17 = $content['h17'];
$content18 = $content['h18'];
$content19 = $content['h19'];
$content20 = $content['h20'];
$content21 = $content['h21'];
$content22 = $content['h22'];
$content23 = $content['h23'];
$content24 = $content['h24'];

if ($content1=="BLANK" || $content2=="BLANK" || $content3=="BLANK" || $content4=="BLANK" || $content5=="BLANK" || $content6=="BLANK" || $content7=="BLANK" || $content8=="BLANK" || $content9=="BLANK" || $content10=="BLANK" || $content11=="BLANK" || $content12=="BLANK" || $content13=="BLANK" || $content14=="BLANK" || $content15=="BLANK" || $content16=="BLANK" || $content17=="BLANK" || $content18=="BLANK" || $content19=="BLANK" || $content20=="BLANK" || $content21=="BLANK" || $content22=="BLANK" || $content23=="BLANK" || $content24=="BLANK")
{}
else
{
echo "There are currently no spots available for $result"; 
}

PHP:

But I still have the exact same problem :/

 

$contentList = array(
    1  => $content['h1'],
    2  => $content['h2'],
    3  => $content['h3'],
    4  => $content['h4'],
    5  => $content['h5'],
    6  => $content['h6'],
    7  => $content['h7'],
    8  => $content['h8'],
    9  => $content['h9'],
    10 => $content['h10'],
    11 => $content['h11'],
    12 => $content['h12'],
    13 => $content['h13'],
    14 => $content['h14'],
    15 => $content['h15'],
    16 => $content['h16'],
    17 => $content['h17'],
    18 => $content['h18'],
    19 => $content['h19'],
    20 => $content['h20'],
    21 => $content['h21'],
    22 => $content['h22'],
    23 => $content['h23'],
    24 => $content['h24']
);

$displayMessage = true;
foreach ($contentList as $item) {
    if ($item == 'BLANK') {
        $displayMessage = false;
        break;
    }
}

if ($displayMessage == true) {
    // show message
}

PHP:

 

It works! Thanks so much!

 

you can use the power of loops and variable variables:

$fieldsCount = 24;
$inUse = false;
$counter = 0;

$content[1]='BLANK';
$content[2]='BLANK';
$content[3]='Test';
$content[4]='BLANK';
/*
 ...
*/

for($counter =1; $counter <= $fieldsCount; $counter +=1)
{
  if($content{$counter} != "BLANK")
  {
    $inUse= true;
    break;
  }
}

if($inUse)
{
  echo 'This field at least is not "BLANK": '.$counter;
}

PHP:

 

or if(empty($variable)) it work too
