Field List Input Problem
Please support our PHP advertiser: PostgreSQL or MySQL? Compare and contrast the two most popular open source databases
Thread Solved |
I am working of a musicians volunteer DB. I have a ADD Volunteer page:
Then I target a page that does the ADD:
I, also, have a EDIT Volunteer page:
Then I target a page that does the UPDATE:
Three issues I need help to resolve:
1) When I select more then one choice from my Instrument field, then select the ADD button, the multiple selections do not carry over to my mySQL table record. Only one value does. The field is a varchar type with plenty of characters allowed.
2) Once I get the data into my DB properly, I need to then be able to have it display properly when I retrieve it on my Update Volunteer Entry page.
3) Eventually, I will establish a Performance Date table in which I will assign Volunteers to performances. When I add a Volunteer:
IF they have multiple instruments they play, I would to provide the user a menu of choices for the field, based of the field Volunteer::Instrument
ELSE
Display it this way: Instrument - Piano
END IF
On a personal note, this is a online DB I am working on for the local Rescue Mission (Homeless Shelter Program). This is my first PHP/mySQL project, so I got much to learn. But once I see how things are done, I catch on pretty quickly.
If there is anyone who would like to volunteer their services to assist me in finishing this project for them, I could make sure you get a Letter of Donated Services from the the Non-Profit organization(tax right off). Just give me a PRIVATE message, if you are willing to help.
Thanks and I appreciate any help that can be offered.

You need to change the name of the instrument select element to "Instrument[]". Then when adding to the database run
On the update page you will need to put the instruments into an array and loop through them checking if they are selected (You should also do this for the add page as it will help keep the data uniform and prevent errors).
ex.
and then echo
Make sure you sanitize your input by adding field validation and using
implode(',',$Instrument); because it will return an array of selected elements. Implode will put them into a comma separated string so it can be put into the database.On the update page you will need to put the instruments into an array and loop through them checking if they are selected (You should also do this for the add page as it will help keep the data uniform and prevent errors).

This is the add page. It submits to itself now since there is no reason to have another page process it.
Put this code on one page:
You can change where the errors and result go. You need to add validation to the forms.
I am working on the edit page.

And my HTML is formatted like this:

Hopefully it something simple in the HTML or PHP.
It's weird though... It shows a List (displayed very narrow) with the correct rows highlighted but NO VALUES ???
Thanks!!!
