If I choose April 3 2010 and Female in the drop-downs. And insert it in my table_1
Assume this are drop-downs
Birthdate: April 3 2010
Gender: Female
Now, when I want to update the record(s) in Edit.php the drop-down value should be also the same
Birthdate: April 3 2010
Gender: Female
But instead it gives me this
Birthdate: January 1 2013
Gender: Male
It seems like a default value whenever I visit in Edit.php. (January 1 2013 Male - are the first items in the dropdowns)
How can I make [April 23 2013 Female] appear in my drop-down Instead of the first values that I didn't choose.
Thanks and sorry for the title I can't think for a good title for this.

Answer 1

Use an if statement to compare each value with your record and then add "selected" to this option

Answer 2

here is the basic concept hope you catch the idea
<?php
$array = array(1=>"January",
2=>"February",
3=>"March",
4=>"April",
5=>"May",
6=>"June",
7=>"July",
8=>"August",
9=>"September",
10=>"October",
11=>"November",
12=>"December");
$stored_data = "2";
foreach($array as $key => $val) {
if($stored_data == $key) {
echo "<option value='$key' selected='1'>$val</option>";
} else {
echo "<option value='$key'>$val</option>";
}
}
?>
