使用具有来自另一个表的字段的表单更新表

Question

I have two tables one tblEmployee and another tblCity .

The two tables are setup like this:

tblEmployee   
-------------
employeeID       
cityID                
name
sex
contactNo

tblCity
-------------
cityID
cityName

I would like to create a form whereby an admin can update an employee's details. The form has a drop down box which is populated by the cityName s in tblCity .

I am struggling coming up with a query to allow the admin to select one of these cities from the drop down which will update the employee's cityID to the corresponding city in tblCity .

Many thanks in advance!

I suspect what you want is to setup the select values like this:

<option value="cityID">cityName</option> 

The cityID will be submitted, and then you put that value in the tblEmployee.cityID .

For example:

<p>
    <select id="sel1">
        <option value="001">Auburn</option>
        <option value="002">Austin</option>
        <option value="003" selected>Dallas</option>
        <option value="004">Houston</option>
    </select>
    <button rel="sel1">Show selected value (with value attribute)</button>
</p>
<p>
    <select id="sel2">
        <option>Auburn</option>
        <option>Austin</option>
        <option selected>Dallas</option>
        <option>Houston</option>
    </select>
    <button rel="sel2">Show selected value (no value attribute)</button>
</p>

$('button').click(function(){
    var $sel = $('#' + $(this).attr('rel')).find('option:selected');
    console.log($sel.val() + ' - ' + $sel.text());
});
