OnChange="submit();" with submit buttons on form a

February 4th, 2006, 5:38 pm

Another brain buster guys (to me this is nuts)

I have a submit button on my form, but i also have a drop down box that needs to change items in some textboxes. here's what i have as code, maybe it would be better if you saw what i was doing.

Code: [ Download ] [ Select ]

<form method=post action="index.php?section=editcourse" name='edit'>
    <table border=0 cellspacing=0 cellpadding=0>
        <tr>
            <td align=center>
                Edit a Course<p>
            </td>
        </tr>
        <tr>
            <td align=left>
                <select name='courses' onChange="edit.submit;">
                    <optgroup label="Courses">
                <?php
                $connect->Connected();
                mysql_select_db('db_courses');
                $result = $connect->query('Select * from tblcourses');
                while ($row = $connect->fetchArray($result))
                {
                    echo "<option value='".$row['CourseID']."'>".$row['CourseCode']."</option>";
                }
                ?>
                $connect->close();
                    </optgroup>
                </select><p>
            </td>
        </tr>
        <tr>
            <td>
                Course Code:&nbsp;<input type=text name=coursecode maxlength=10 value=<?php ?>><p>
            </td>
        </tr>
        <tr>
            <td>
                Course Name:<input type=text name=coursename maxlength=50><p>
            </td>
        </tr>
        <tr>
            <td colspan=2 align=center>
                <input type=submit value="Submit" name=submit>
                <input type=reset value="Reset" name=reset>
            </td>
        </tr>
    </table>
</form>

1. <form method=post action="index.php?section=editcourse" name='edit'>
2.     <table border=0 cellspacing=0 cellpadding=0>
3.         <tr>
4.             <td align=center>
5.                 Edit a Course<p>
6.             </td>
7.         </tr>
8.         <tr>
9.             <td align=left>
10.                 <select name='courses' onChange="edit.submit;">
11.                     <optgroup label="Courses">
12.                 <?php
13.                 $connect->Connected();
14.                 mysql_select_db('db_courses');
15.                 $result = $connect->query('Select * from tblcourses');
16.                 while ($row = $connect->fetchArray($result))
17.                 {
18.                     echo "<option value='".$row['CourseID']."'>".$row['CourseCode']."</option>";
19.                 }
20.                 ?>
21.                 $connect->close();
22.                     </optgroup>
23.                 </select><p>
24.             </td>
25.         </tr>
26.         <tr>
27.             <td>
28.                 Course Code:&nbsp;<input type=text name=coursecode maxlength=10 value=<?php ?>><p>
29.             </td>
30.         </tr>
31.         <tr>
32.             <td>
33.                 Course Name:<input type=text name=coursename maxlength=50><p>
34.             </td>
35.         </tr>
36.         <tr>
37.             <td colspan=2 align=center>
38.                 <input type=submit value="Submit" name=submit>
39.                 <input type=reset value="Reset" name=reset>
40.             </td>
41.         </tr>
42.     </table>
43. </form>

This ?

Code: [ Download ] [ Select ]

onChange="this.form.submit();"

February 4th, 2006, 6:23 pm

No go. that didn't work. That looked to me that it would work

Ok.
What should happen after someone does what ?
What should be doing the what that happens ?

February 4th, 2006, 10:45 pm

Alright, here's my situation to make things clear

In the editing section of my PHP script, the user will be able to select from a drop down list of what they want to edit, once they select what they want, the value of the drop down list will be the ID that will relate to a table in a MySQL database. On that change to the course that the user desiers, this will in turn fill 2 text boxes, the course code, and its description.

But this can only happen, in my opinion during a submit. If you have another way, i'm willing to try anything.

Hope that is clear enough

Code: [ Download ] [ Select ]

echo "<option value='".$row['CourseID']."'>".$row['CourseCode']."</option>";

I get the feeling 'CourseID' is an integer identifier of the course.
What would 'CourseCode' be ?

Are both of thoose values the ones that would fill the textboxes ? Or does a trip to the server need to be made to get the 'Course Name' ?

CourseCode is a string that is 10 char long....

I have the coursecode displaying in the drop down list, and tested to see if the id was set properly (go javascripts alert )

I just need it to, onChange, change accordingly, keep in mind, that i have a submit button. When I remove it, it works...so i don't know anymore

You remove the submit button & it works ?

Try replacing that submit button with a normal button that has a submit attached ?

Code: [ Download ] [ Select ]

<input type="button" value="Submit" name="submit" onclick="this.form.submit();">

I'm pretty confused at this point.

what i ended up doing is get rid of the submit button, and when the onchange happened, i had it go to a different page, passing the value.

Appreciate the help joebert, you help didn't go in vain.

I think what's happening here is that the name of the Submit element is overriding the submit() form function. By renaming the Submit element, I was able to get both the onChange and Submit button submissions to work.

Code: [ Download ] [ Select ]

<input type="button" value="Submit" name="submitForm" onclick="this.form.submit();">
