[php]4ft - 121 cm[/php]

are you really storing imperialistic numbers in your db…?

#3

Curious why you are doing it this way. If you want to use a drop down, why not separate the primary and secondary numbers? Or Have a selection to choose either or and use a conversion?

Going the route you are, a look up is the option you want.

#4

hi i’m new in this field how to do this! do i need to value=“4ft - 121 cm” in this form right?

#5

ok

#6

how? when dropdown from data base…id and name… value=“id” name =namehere? how to do this?

#7

If the dropdown is being populated by a data table, you use the id and display name. When you insert the record, you use the ID from the table as a foreign key. When you select (view) their data, it just joins on the table.

tbl_height
ID | value
1 | 6ft

tbl_member
ID | name | height
2 | astonecipher | 1

SELECT m.name, m.height FROM tbl_member m INNER JOIN tbl_height h ON m.height = h.ID WHERE m.ID = 2

i didn’t understand! here is my dropdown country list <?php

$stmt = $DB_con->prepare("SELECT * FROM countries");
$stmt->execute();
while($row=$stmt->fetch(PDO::FETCH_ASSOC))
{
	?>
    <option value="<?php echo $row['id']; ?>"><?php echo $row['name']; ?></option>
    <?php
}

?> how to retain input value! after form submit…!

#9
<?php $stmt = $DB_con->prepare("SELECT * FROM countries"); $stmt->execute(); while ($row=$stmt->fetch(PDO::FETCH_ASSOC)) { $selected = ''; if(!empty($_POST['country']) and $_POST['country'] == $row['id']) { $selected = ' selected="selected"'; // hah! } echo ''.$row['name'].''; } ?> here is!
#10

Way to go!
