dynamic dropdown

[calmchess]

how do i code a dropdown box with php so that i can add as many fields as i like without modifying the html?

i envision an array in ad database being brought out exploded and the resulting  array is used to populate the dropdown.

coding all the database stuff isn't necessary if you can just show me how to populate the dropdown box with an array.

Hi

 

Assuming you do not need a seperate specified value:-

 

$SomeArray = array('London','Paris','Rome');
$OutDropDown = "<select name='DropDownName'><option>".implode("</option><option>",$SomeArray)."</option></select>";

 

If you want a way to do it with a value matching an ID then not sure of a way to do it in a single line

 

$SomeArray = array(1=>'London',2=>'Paris',4=>'Rome');
$OutDropDown = "<select name='DropDownName'>";
foreach($SomeArray AS $SomeId=>$SomeName)
{
$OutDropDown .= "<option value='$SomeId'>$SomeName</option>";
}
$OutDropDown .= "</select>";

 

 

All the best
