Creating 'Other' option in select list

Thread began 12/05/2009 7:44 pm by andy.schofield283961 | Last modified 12/18/2009 12:28 pm by Jason Byrnes | 1133 views | 8 replies |

Creating 'Other' option in select list

Not sure if this is the right place but is there a way to add a 'other' option to the select lists that DA creates which can then be modified to record the 'other' option so you are not limited to just the current options in the select list.

Thanks

Andy

that *could be done, but whatever is added in the "other" textbox will not be added to the list for future use.

If you want to have it added to the list for future use, you would be better of creating an insert page for the select list table.

For the small amount of data this would represent then i wouldnt split into seperate table, i would just populate menu based on a distinct sql of the field for the drop down. So in that case if the whole page was added to the record of the table then it would be populated.

Can you give me any idea how best to achieve this with data assist. I appreciate that anything can be done but was wondering if there were any tools / instructions to accomplish this.

If not I'll figure it out but 'dont ask dont get' :-)

I apologize, I read your last reply 4 or 5 times and I'm not sure I understand what you are trying to accomplish. Sorry to make you repeat yourself, but can you spell out what you want to happen?

Jason,

Please dont apologise I havent articulated this very well, so I'll try and do it better...

I have uploaded an example of what I am trying to do.

My simple take on this was:

Create the pages with dataAssist, hide the 'category' text box created by WebAssist.

create a dropdown list with static 'other' option and dynamic recordset selecting distinct values of category within the table.

When the user selects an options from the select list it changes the value of the 'category' hidden text box.

If the user selects other the hidden 'category' field is made visible and value cleared, ready for the user input.

if the user selects one of the other categories from the drop down, the field is re-hidden and follows the previous described behaviour.

I hope with the attachment what I am attempting to do is clearer.

I thought that by using DataAssist and Validation toolkit this would be doable.

Can you advise please.

Thanks again for the help

You need to use required / not blank validation on the onchange event of the Select list. Then nuse the Show Hide layer response.


I have attached a sample file that demonstrates how to accomplish this, see the attached file.

Jason,

Thanks for the reply, I can see what you have done here but (there is always a but I'm afraid). DataAssist wizard you have to map the form fields to the database fields one to one. So in your example you gave we have two different fields writing for the same value.

What is the best way to get this into the DataAssist wizard using your method.

My original idea was that to change the text held in the other field with that of the select list regardless of the selection. That way I can map the 'other' field (visible or not) to via the DataAssist wizard.

Thanks again for the reply

Look in code view at the sample page ;)

Right after the closing form element, there is php code that you can use for accomplishing this.

When you bind to a form element in the DataAssist insert or update record behavior, it adds code that looks like:

php:
<?php echo ((isset($_POST["category"]))?$_POST["category"]:""); ?>



this is a ternary expression that says:
does the category form element have a value?
Yes: use the category form element a value.
No: use a blank string

The code I have added at the bottom of the page takes that a step further:

php:
<?php echo((isset($_POST["category"])&&$_POST["category"]!="")?$_POST["category"]:$_POST["other"]) ?>



this basically says:
does the category form element have a value that is not a blank string?
Yes: use the category form element a value.
No: use the other form element a value.

you can use this code for the category column in the Insert or Update record behavior.
