Loop help

[Vivid Lust]

Hey!

 

I got some help here: http://www.phpfreaks.com/forums/index.php/topic,223290.0.html

 

And here's my loop:

 

for($i = 1; $i <= $checks; ++$i){
   if ($site[$i] != ""){
      $foo[$i] = $site[$i];
   }
}

 

The problem is, is that if $site[1] is equal to "", then $foo[1] becomes "" ... I dont wont this to happen, I want $foo[1] to store the first $site[] which has a value which isnt "".

 

Thanks for all the help guys.

Anyone?

if $site[1] is equal to "", then $foo[1] becomes "" ... I dont wont this to happen,

 

It doesn't happen.  Look at your code.  You only assign $foo[$i] = $site[$i] when $site[$1] IS NOT EQUAL to "".

 

if ($site[$i] != ""){
      $foo[$i] = $site[$i];
   }

for($i = 1; $i <= $checks; ++$i){
   if (!empty($site[$i])){
      $foo[1] = $site[$i];
      break;
   }
}

[Vivid Lust]

that just stores the first value in the $foo[1] ... what about the others?

thanks!

I want $foo[1] to store the first $site[] which has a value which isnt "".

 

sounds like you need to explain what you want a little better then....

 

...maybe you meant this:

for($i = 1; $i <= $checks; ++$i){
   if (!empty($site[$i])){
      $foo[$i] = $site[$i];
   }
}

Still doesnt work, and sorry

 

Code(part of):

 

<?php
for($i = 1; $i <= $checks; ++$i){
   if (!empty($site[$i])){
      $foo[$i] = $site[$i];
   }
}

// set some variables
$user_pass = $_SESSION['user'];
$user_email = $_SESSION['user2']; 

$sql ="UPDATE users SET bg=\"$back\",box1=\"$foo[1]\",box2=\"$foo[2]\",box3=\"$foo[3]\",box4=\"$foo[4]\",box5=\"$foo[5]\",box6=\"$foo[6]\",box7=\"$foo[7]\",box8=\"$foo[8]\",box9=\"$foo[9]\",box10=\"$foo[10]\",box11=\"$foo[11]\",box12=\"$foo[12]\",box13=\"$foo[13]\",box14=\"$foo[14]\",box15=\"$foo[15]\" WHERE email=\"$user_email\" AND pass=( \"$user_pass\" )";
$query=mysql_query($sql, $link)
or die(mysql_error());
?>

 

If i have one box checked (please referr to post linked in first post), it is stored in the table column in relation to when it has been counted.

 

Help anyone? Thanks

ok, after doing a little testing, it appears that checkboxes that are unchecked are not added to the $_POST array at all. so, if you assign a $_POST[] that doesn't exist (of a checkbox that wasn't checked) to $site[$i], then $site[$i] would contain NULL (and you should probably get a warning). so maybe using is_null() instead of !empty() will work.

[Vivid Lust]

just tried that, same result as last  thanks for the suggestion though

[Vivid Lust]

Ideas Anyone?

[bobbinsbro]

could you please var_dump($site, $foo) at the end of the code?

[Vivid Lust]

 

My loop code:

 

<?php
for($i = 1; $i <= $checks; ++$i){
   if (!isset($_POST['$i'])){
      $foo[$i] = $site[$i];
   }
}
?>

 

When one box is checked this displays:

 

array(15) { [1]=>  NULL [2]=>  string(18) "http://www.bbc.com" [3]=>  NULL [4]=>  NULL [5]=>  NULL [6]=>  NULL [7]=>  NULL [8]=>  NULL [9]=>  NULL [10]=>  NULL [11]=>  NULL [12]=>  NULL [13]=>  NULL [14]=>  NULL [15]=>  NULL } array(15) { [1]=>  NULL [2]=>  string(18) "http://www.bbc.com" [3]=>  NULL [4]=>  NULL [5]=>  NULL [6]=>  NULL [7]=>  NULL [8]=>  NULL [9]=>  NULL [10]=>  NULL [11]=>  NULL [12]=>  NULL [13]=>  NULL [14]=>  NULL [15]=>  NULL }

 

Thanks for any help.

<?php
for($i = 1; $i <= $checks; ++$i){
   if (!empty($_POST[$i])){
      $foo[$i] = $site[$i];
   }
}
?>

[bobbinsbro]

try this:

$site2 = array_unique($site);
$loopCount = count($site2);

for($i = 1; $i <= $loopCount; ++$i){
   if ($site2[$i] != NULL){
      $foo[$i] = $site2[$i];
   }
}

 

this should at least get rid of a while lot of null elements...

Hi, still not working, still inserts a blank value before the actuall value

 

Thanks for the work though guys

[sasa]

try

<?php
$foo = $site;
for($i = 1; $i <= $checks; $i++) if (!$site[$i]) unset($foo[$i]);
$foo = array_values($foo);
print_r($foo);
?>

or look my last post

[Vivid Lust]

Works, thanks loads!

[Vivid Lust]

The only problem now, is that when having 20 checkboxes, it only works for the first 15! I've add all the relevant stuff

[sasa]

are you change value of variable $checks to 20?
