[Resolved] foreach function

[Jon12345]

I have some code as follows:

foreach ($nixxie->ads as $ad) {

blah blah

}

I want to change that code so for the first item it processes different code, for the second item, it does something different again, but for all the remaining items, it does the same thing.

How do I modify this code to do that?

Thanks,

Jon

I think this will work...

foreach($nifty->item as $key => $value){
  if($key == 0)
    //do something
  if($key == 1)
    //do something

  //everything else here
}

[Jon12345]

Won't I need to have something after

if($key == 1)
//do something

as it doesn't know where 1 ends and the rest begins?

i.e. do I need to use else or something like that?

[Kudose]

It knows where it ends.

With each pass, the $key is going to get higher since it is the key to the array.

i.e.

<?php
$item = array("Hello", "World", "Testing", "123");

foreach($item as $key => $value){
  //check for the first key
  if($key == 0)
    echo 'The key is zero, but I wont return the value';
  //check for the second key
  if($key == 1)
    echo 'The key is one. Still no value output.';

  echo 'You win.  Here are the values too.';
  //do the rest
  echo 'Key -> '.$key.'<br>Value -> '.$value.'<br><br>';
}
?>

[Jon12345]

Ok, so the if statement will only process the next line? and ignores subsequent lines?

[Kudose]

Correct. It only follows to the first semicolon.

[Jon12345]

Gotcha thanks.

A quick one...

foreach ($feed->ads as $ad)

My code is as above. How would that translate to

foreach($item as $key => $value){ 

???

[Kudose]

I was just using a general example.

Basically, $item is the array your using the foreach on.

$key => $value will store the $item subscript into $key, and the $item value in $value.

So...

foreach($feed->ads as $key=>$value){

//this should work

}

[Jon12345]

Ok, that makes sense. But on my code if $key=0, I have about 10 lines of code to run. Same for if $key=1 or other.

So I will need to use an alterntive to the if statement, one which lets me use {}. Any suggestions? Switch?

[Kudose]

Yes, if your not executing one line, you need to use braces for the if statement.

[Jon12345]

Hmm, something is not working. I've put in the {}. But now I get displayed two rows but without the data.

I have this as part of the code:

{$ad['CLICKURL']}

Any ideas?

[Kudose]

Put up some more code please.

[Jon12345]

foreach($feed->ads as $key => $value)
  {
    if($key == 0) {
    echo "<table border='0' cellpadding='5' cellspacing='0' bgcolor='#CCCCCC' class=\"nx\">\n";
    echo "<tr class=\"nx\">\n";
    echo "<td colspan='2' class=\"nx\">\n";

echo "<span class=\"nx-title\">{$ad['TITLE']}</span><br><span class=\"style3\">{$ad['DESCRIPTION']}</span><br>\n";
echo "</td></tr>\n";	

echo "<tr class=\"nx\">\n";
echo "<td class=\"nx\">\n";	
echo "<a class=\"style5\" href=\"{$ad['CLICKURL']}\">{$ad['URL']}</a>\n";
echo "</td>\n";
echo "<td class=\"nx\">\n";
echo "<div align='right'>";
echo "<a class=\"nx\" href=\"{$ad['CLICKURL']}\">more info</a>\n";
echo "</div>";
echo "</td></tr>\n";		
echo "</table>\n";
echo "<br>";
}

if($key == 1) {
echo "<table border='0' cellpadding='5' cellspacing='0' bgcolor='#CCCCCC' class=\"nx\">\n";
echo "<tr class=\"nx\">\n";
echo "<td colspan='2' class=\"nx\">\n";

echo "<span class=\"nx-title\">{$ad['TITLE']}</span><br><span class=\"style3\">{$ad['DESCRIPTION']}</span><br>\n";
echo "</td></tr>\n";	

echo "<tr class=\"nx\">\n";
echo "<td class=\"nx\">\n";	
echo "<a class=\"style5\" href=\"{$ad['CLICKURL']}\">{$ad['URL']}</a>\n";
echo "</td>\n";
echo "<td class=\"nx\">\n";
echo "<div align='right'>";
echo "<a class=\"nx\" href=\"{$ad['CLICKURL']}\">more info</a>\n";
echo "</div>";
echo "</td></tr>\n";		
echo "</table>\n";
echo "<br>";
}

  }

[Kudose]

$ad needs to be $value.

Also, I would concat. your variables in, instead of using braces.

ie.e

//your line
echo "<a class=\"style5\" href=\"{$ad['CLICKURL']}\">{$ad['URL']}</a>\n";

//my line
echo '<a class="style5" href="'.$value['CLICKURL'].'">'.$value['URL'].'</a>\n';  

But, to each thier own.

Without getting into the use of tables and span tags, here is my suggestion:

<?php
  foreach($feed->ads as $key => $value)
  {
    if($key == 0) {
?>
    <table border='0' cellpadding='5' cellspacing='0' bgcolor='#CCCCCC' class=\"nx\">
    <tr class=\"nx\">
    <td colspan='2' class=\"nx\">

<span class=\"nx-title\"><?php echo $ad['TITLE'];?></span><br>
<span class=\"style3\"><?php echo $ad['DESCRIPTION'];?></span><br>
</td></tr>    

<tr class=\"nx\">
<td class=\"nx\">    
<a class=\"style5\" href=\"<?php echo $ad['CLICKURL'];?>\"><?php echo $ad['URL'];?></a>
</td>
<td class=\"nx\">
<div align='right'>
<a class=\"nx\" href=\"<?php echo $ad['CLICKURL'];?>\">more info</a>
</div>
</td></tr>        
</table>
<br>
<?php
    } elseif($key == 1) {
?>
    <table border='0' cellpadding='5' cellspacing='0' bgcolor='#CCCCCC' class=\"nx\">
    <tr class=\"nx\">
    <td colspan='2' class=\"nx\">

<span class=\"nx-title\"><?php echo $ad['TITLE'];?></span><br>
<span class=\"style3\"><?php echo $ad['DESCRIPTION'];?></span><br>
</td></tr>    

<tr class=\"nx\">
<td class=\"nx\">    
<a class=\"style5\" href=\"<?php echo $ad['CLICKURL'];?>\"><?php echo $ad['URL'];?></a>
</td>
<td class=\"nx\">
<div align='right'>
<a class=\"nx\" href=\"<?php echo $ad['CLICKURL'];?>\">more info</a>
</div>
</td></tr>        
</table>
<br>
<?php
    } else {
      // do your "other" stuff here
    }
  }
?>

Just a little easier to read, in my opinion

[Jon12345]

It works thank you!
