 Posted: Fri Nov 16, 2007 7:58 pm Post subject: Getting value of <option> in <select> tag |
 |
|
|
Let's say I have a select statement as follow:
| Code: |
<select name="testing">
<option value="1">Test1</option>
<option value="2">Test2</option>
<option value="3">Test3</option>
<option value="4">Test4</option>
</select>
|
and this select tag is in a form using method="POST".
Is it possible to get the text of the option selected when submitting the form?
I know that if I do $_POST['testing'] I will get back 1,2,3 or 4 but I would like to get Test1, Test2, Test3 or Test4 instead.
Regards |

And in my case, that is not possible since the value of the options will be used for an SQL query.
Ex:
ID: 1 Name: Josef
ID: 2 Name: Nicholas
ID: 3 Name: Pauline
if 1 is selected, then update that row and once updated say: Student Josef was updated successfully.
I know i have the option to create another SELECT statement to get the name again but I would like to avoid that if possible |

You have to load the names so u can select them no?
so what you can do is
| Code: |
<option value="<?echo $row['student_id']; ?>"><?echo $row['student_name'];</option>
|
.. Then
| Code: |
<?
echo " $_POST['selected_option'] was updated successfuly; "
?>
|
Problem solved

| like that, if I have an SQL statement I can only update by student_name and hence, any duplicate names will be updated too... |

Many approaches to take here..
You could store the loaded id/name pairs in the session as an associative array then access the one you need when you want to display the name but you only have the id.
Alternatively, you can add a prefix to the values in the select.. so your values will be for example "test" + the id (test1, test2 etc. When you get the values in PHP extract the id with a simple function like substr, while using the whole value for the name.
Yet another option is to use some JavaScript.. place a hidden field in the form, and when the user clicks the button to save/edit etc, extract the text of the selected value and place it in the hidden field. Be careful though cos users may disable JavaScript on the browser.. |
