echo multiple array values

[goltoof]

For option1 I need to echo not just field1, but field2, field4, etc..  What's the proper way to do this?

<?php
$field_array = array(
'field1' => '<tr><td>Field 1:</td><td><input type="text" name="field1" /></td></tr>',
'field2' =>  '<tr><td>Field 2:</td><td><input type="text" name="field2" /></td></tr>',
'field3' =>  '<tr><td>Field 3:</td><td><input type="text" name="field3" /></td></tr>',
'field4' =>  '<tr><td>Field 4:</td><td><input type="text" name="field4" /></td></tr>',
'field5' =>  '<tr><td>Field 5:</td><td><input type="text" name="field5" /></td></tr>',
);
?>

<?php
if(isset($_GET["q"])){
?>
<form method="post" action="update.php">
	<table>
		<?
		switch ($_GET["q"]) {
			case "option1" :
				echo $field_array['field1'];
			break;
			case "option2" :
				echo $field_array['field1'];
			break;
			}
			?>
	</table>
	<input type="submit">
</form>
<?php
}
?>

why can't you simply echo other keys?

 

<?php
$field_array = array(
'field1' => '<tr><td>Field 1:</td><td><input type="text" name="field1" /></td></tr>',
'field2' =>  '<tr><td>Field 2:</td><td><input type="text" name="field2" /></td></tr>',
'field3' =>  '<tr><td>Field 3:</td><td><input type="text" name="field3" /></td></tr>',
'field4' =>  '<tr><td>Field 4:</td><td><input type="text" name="field4" /></td></tr>',
'field5' =>  '<tr><td>Field 5:</td><td><input type="text" name="field5" /></td></tr>',
);
?>

<?php
if(isset($_GET["q"])){
?>
<form method="post" action="update.php">
	<table>
		<?php
		switch ($_GET["q"]) {
			case "option1" :
				echo $field_array['field1']. "<br />";
                                        echo $field_array['field2']; // etc.......
			break;
			case "option2" :
				echo $field_array['field1'];
			break;
			}
			?>
	</table>
	<input type="submit">
</form>
<?php
}
?>

I can but I was wondering if there was another way to do it without having to echo each value individually.  No way to just echo once and just list every value i want in one line?

[AyKay47]

there are several ways to do this, however simply echoing the array elements is the simplest and shortest method for this specific instance

[goltoof]

The actual script I'm working on involves 50 or so values to display  for each option, with 10 options, and each option has different values.  There are 200 values in total between the 10 options.

 

I think it's just a little daunting having to echo each array individually 50 times for each option, that's a lot of echos and makes for a very ugly script...

You can use a loop, such as a for loop

$field_array_count = count($field_array);
for($i = 1; $i < $field_array_count; $i++)
{
      echo $field_array['field' . $i];
}

 

However what you doing in each option?

I don't think a loop applies here since I'm not displaying every field for each option.  Each option contains up to 50 fields that differ from other options. 

 

option1 (field1, field2, field3, field4, field27, field28, field29, field56, field88, field89, etc)

option2 (field1, field2, field9, field10, field11, field23, field34, etc)

option3 (field1, field2 field3, field36, field37, field52, field56, etc)

if you really want to use a loop, you can take what wildteen88 suggested or something like it, and incorporate the continue statement for the instances that you will not want to echo

I'll look into it.  An example as it pertains to the situation would be extremely helpful.  I'd like to see if it's at least more practical than inidividual echos.

there are a few examples in the link that I provided
