This handy PHP function will reduce the amount of typing
you do when you are designing HTML forms. While all you need to
enter is the field name and an array of select options for the function
to work, it offers the flexability to build very complex select tags if
needed. The selected parameter allows for a default option to be
selected. The "option" parameter allows for extra arguments to be
inserted inside of the input tag while the "prepend" and "append"
parameters allow for additional output to be added before and after the
tag. The indent tag allows for indenting the output HTML for
easier reading.

$field = $indent . $prepend . "<select
name=\"$name\"";
if($option){
$field .= " $option";
}
$field .= ">\n";
for ($x = 0; $x < count($select_array); $x++) {
if ($select_array[$x] ==
$selected) {
$field .=
$indent . "\t<option selected>$select_array[$x]</option>\n";
}
else {
$field .=
$indent . "\t<option>$select_array[$x]</option>\n";
}
}
$field .= $indent . "</select>" . $append .
"\n";
return $field;
}

| Usage: |
| |
echo build_select_field('sample', array('Option 1', 'Option 2', 'Option 3'), 'Option 2', 'multiple', '<b>Options: </b>', '<br />', "\t\t\t");
|
| |
|
|
Result:
|
| |
<b>Options: </b><select name="sample">
<option>Option 1</option>
<option selected>Option 2</option>
<option>Option 3</option>
</select><br />

Notes:
|
| |
This is only really practical if you are planning to add
a lot of select fields manually. Using a loop to build a form
would be a good substitute for this kind of manual form creation. |
