How I explode this kind of string in PHP? - php

Question

I have a dropdown to display price ranges for searching.
HTML for dropdown:
<select name="price">
<option value="">All (-)</option>
<option value="">Rs.400 to Rs.1,000 (3)</option>
<option value="">Rs.1,000 to Rs.2,000 (6)</option>
<option value="">Rs.2,000 to Rs.4,000 (1)</option>
<option value="">Rs.4,000+ (1)</option>
</select>
Using this option values, now I need to separate first and second price from user selection.
Eg. If someone select Rs.400 to Rs.1,000 (3), then I need to get 400 and 1,000.
Can anybody tell me how can I do this in php. I tired it with php explode. but I could not figure this out correctly.
Hope somebody may help me out.
Thank you.

Answer 1

What about something like this:
HTML
<select name="price">
<option value="all">All (-)</option>
<option value="400|1000">Rs.400 to Rs.1,000 (3)</option>
<option value="1000|2000">Rs.1,000 to Rs.2,000 (6)</option>
<option value="2000|4000">Rs.2,000 to Rs.4,000 (1)</option>
<option value="Over">Rs.4,000+ (1)</option>
</select>
PHP
<?php
//Get the data from the form
$price = $_POST['price'];
$prices = explode("|", $price);
?>
For example, if the user selects "Rs.400 to Rs.1,000", the value of $prices will be:
$price[0] = "400";
$price[1] = "1000";
I hope that helps. If it doesn't, I suppose I wasn't clear on what you were asking.

Answer 2

Inspired by a previous answer. I'd suggest.
HTML
<select name="price">
<option value="|">All (-)</option>
<option value="400|1000">Rs.400 to Rs.1,000 (3)</option>
<option value="1000|2000">Rs.1,000 to Rs.2,000 (6)</option>
<option value="2000|4000">Rs.2,000 to Rs.4,000 (1)</option>
<option value="4000|">Rs.4,000+ (1)</option>
</select>
PHP
<?php
function get_numeric($val) {
if (is_numeric($val)) {
return $val + 0;
}
return false;
}
$price_selected = isset($_REQUEST['price']) && trim($_REQUEST['price'])!="" ? $_REQUEST['price'] : "|"; // sets a default value
list($lower, $upper) = array_map('get_numeric',explode('|', $price_selected, 2));
var_dump($lower); // false when there's no lower limit
var_dump($upper); // false when there's no upper limit
?>
