loop to view multiple results from one column?


Recommended Posts

Confusing I know.  Here's what I've got.  I used the Dreamweaver Developer Toolbox in a form that has multiple checkbox results entered into one db column.  Id's are entered into this column that join with another table to connect the text to these id's.


So the column looks like this: 1,5,7,8.

The corresponding text is red, blue, green, yellow.


I'm using the str_replace to change the comma to a <BR> so the results read in separate rows.  Where I'm drawing a blank is how to show all these results as text.  So far I've only been successful showing this:







And only the first result as text (red).

I'd like the results to look like this:







I'll take any help pointing me in a correct direction.

Depends how flexible you want it to be.


You could use:-


$colours = array(1=>'red',5=>'blue',7=>'green',8=>'yellow');
$Fields = explode(',',$row['id']);
foreach($Fields as $Field)
  echo $colours[$Field]."<br />";


Trouble is that this requires hard coded lists of colours.


It would be better if there was a separate table containing a separate row for each ID for each row from the current table. Then you could just use a JOIN against a table of colours to get them.


All the best

There is a separate table that the values do correspond to.  And that's definitely way I'd like to go.


This is the column I'm pulling the values from $row_rsKSA['knowledge_ksa']


Here's the equivalent of what I've got:

Table 1  = id, color

Table 2 = id, color_id


The color_id has the multiple values (1,5,7)

You really need to split up the field that has multiple values onto a seperate table with one row per value.


Eg, while you have something like:-



Id - Name - ColourId

1 - Fred - 1,2,3,4,5

2 - Burt - 2,4,6


What you want is something like:-



Id - Name

1 - Fred

2 - Burt



Id - Table1Id - ColourId

1 - 1 - 1

2 - 1 - 2

3 - 1 - 3

4 - 1 - 4

5 - 1 - 5

6 - 2 - 2

7 - 2 - 4

8 - 2 - 6


While it is possible to do a join against the various values from the comma seperated column, the code to do it is going to be dog slow and isn't particularly friendly for anyone who has to modify it in the future.


All the best
