Array problem

[crowds40]

For some reason this array will only return 'white'. Is there a problem with the code? 

 <?php
  $test = array('blue','green','white');
foreach($test as $val)
 ?>

 
 <?php
echo "$val"; ?>

Yes, you need to wrap echo "$val";  in curly braces

 <?php

$test = array('blue','green','white');
foreach($test as $val)
{
    echo "$val";
}
?>

If you are to go in and out of PHP mode then you should format your code like

<?php

$test = array('blue','green','white');

?>

<ul>
<?php foreach($test as $val): /* opens foreach block */ ?>
  <li><?php echo "$val"; ?></li>
<?php endforeach; /* closes foreach block */ ?>
</ul>

Why are you exiting php mode in your foreach??

 

<?php
$test = array('blue','green','white');
foreach($test as $val)
   echo "$val<br>";
exit();

I had to take it one step further to:

 <?php 
  $test = array('blue','green','white');
foreach($test as $val)
$testValues[] = "color=$val"; 

echo "<a href='?";
echo join("&", $testValues);
echo "'>Color</a>"; ?>

The url is "website.com?color=blue&color=green&color=white"

 

Again this this will only return the white and not the blue, green, and white. Hope that makes sense. Any ideas?

Works for me. Although you might want to change & to just

[mac_gyver]

your link is repeating the color= parameter, so each value in turn is overwriting the previous value when php populates the $_GET['color'] variable.

 

 

what overall goal are you trying to accomplish? a separate link for each possible color or one link that contains all the values from the array?

Hi mac_gyver,

 

I am trying to have one link that will contain the 'blue' 'green' and 'white' values from the array

[mac_gyver]

what format do you want the link to be in, because it's impossible to write code without knowing what end result you are trying to produce.

[crowds40]

I don't exactly know what you mean by what format. Sorry I am new to this.

[Ch0cu3r]

So you want to output a separate link for each color in your array?

<?php

$colors = array('blue','green','white');
foreach($colors as $color)
{
    echo '<a href="page.php?color='. $color. '">' . $color. '</a><br />';
}
?>

[crowds40]

Thanks for the response. I wish to output all three colors (blue,green,white) in the same link from the array if possible

You need to answer mac_gyver question here, as you replies make no sense.

@crowds40, your question lacks context and definition that would would allow us to answer it (it didn't even start as being a question about making one url, which means that the answers given at first didn't apply to the actual problem.)

 

you have an array of one or more colors. you either need to combine them into one url parameter, i.e. ?color=blue|green|white or you need to use a separate parameter in the url for each one (which could actually be an array name so that php would receive an array when the url is submitted.)

 

which method you use depends on what you are using the values for, how cluttered/long you want to make the url, and how much code you want to write to extract the values when the link gets submitted.
