Get the Selected value from the Drop down box in PHP

Question

I am populating a Drop Down Box using the following code    lt select id  select catalog  gt   lt  php   array all catalogs    db- gt get all catalogs    foreach  array all catalogs as  array catalog    gt   lt option value   lt     array catalog  catalog key     gt   gt  lt    array catalog  catalog name     gt  lt  option gt               Now how can I get the selected option value using PHP  I have the code to get the selected item using Javascript and jQuery  because I want the selected value to perform a query in database   Any help will be much appreciated  Thank you very much

Couldn t you just pass the  a name attribute and wrap it in a form   lt form id  quot form quot  action  quot do stuff php quot  method  quot post quot  gt       lt select id  quot select catalog quot  name  quot select catalog query quot  gt       lt  php  lt  lt  lt INSERT THE SELECT OPTION LOOP gt  gt  gt    gt       lt  select gt   lt  form gt   And then look for   POST  select catalog query

You need to set a name on the  lt select gt  tag like so    lt select name  select catalog  id  select catalog  gt    You can get it in php with this     POST  select catalog

You have to give a name attribute on your  lt select   gt  element  and then use it from the   POST or   GET  depending on how you transmit data  arrays in PHP  Be sure to sanitize user input  though
