[PHP] Fields into Combo Box
Hi,
I just have a couple of questions that I hope some people will know the answers to.
1. I am hoping to read the entire range of values from a field in my MySQL table into
a combo box on my form, but I am not sure how. On top of that, I want the user to
select one value from this list, press next, and the combo box reappears with the full
list minus the chosen value. The user then chooses another, presses next, and the
combo box then appears again, minus the two chosen values. This loop continues until
flagged.
Does anyone have any ideas how I can do this?
2. I have created a session variable $session. This is an array. I have a dynamic
variable, ${"myvalue$counter"}, which has particular values assigned. The number of
instances varies depending on the data in the database, so it is difficult to go
through and assign each value to the session variable manually, eg
$session["myvalue1"], $session["myvalue2"], etc. Is there any way I can incorporate
dynamic variable names into the array structure like above. I have searched around,
but I am not really sure what this would come under.
3. This is similar to above, but it refers to functions. Is it possible to have
dynamic function names that actually change from where you call it?
eg. $value=1;
(call function from within another file)
function name$value (...)
$value=2;
(call same function from within the same file as before)
function name$value (...)
Is this possible with php?
Thank you very much for your time,
Michael.

[PHP] Combo Box containing field
Hi, Does anyone know how I can create a combo box in my php file that reads the options in from a database field? I can create combo boxes fine containing values that I enter, but I want it to read the values from the database into the drop down box for the user to select. Thanks, Michael.
[PHP] Dynamic Arrays?
Hi, I have a bit of a dilemma. I have a number of array attributes, eg. $arrayname["var1"], $arrayname["var2"], $arrayname["var2"], etc. up to 58, and I want to write these into the database. What I am hoping to do is create a counter that goes through the insert routine, updating the numerical value of "var". The problem is.. everything I have tried hasn't worked. I have tried things like... $counter=1; $arrayname[["var".$counter1]]; $arrayname["var$counter1"]; ...and variations thereof. Everything I have tried has failed. PLEASE can someone help??
[PHP] Back Button Dilemma's
Hi Guys, I know everywhere it says that it is not possible to actually disable the back button, and people have offered some solutions that have not worked for me, this is why I am emailing this list. I have a form which displays the same page with new content (controlled by a counter) in a loop until an exit point is reached. When the user clicks back on the browser the counter still increments and the screen continues like the user pressed the continue button (which is the process I want the user to take). The problem is the user did not make a selection and this is where the problem lies (it takes the default, which throws the whole process out of whack). The question I am asking is how can I prevent the user trying to go back? Is there any code out there which can counter this action (and not cause my counter to increment, thus moving the user to the next screen)? Is there any way to detect that the back button/option has been selected and display a "warning" type page before going back to where the user is? The forward counter action does not really fix my problem. Thanks, Michael. Chief Information Officer, RealGM, Inc. http://www.realgm.com
[PHP] Mail Function
Hi, Tonight was my first attempt at using the mail() function, and running the script I had no problems with execution. Everything seemed to go smoothly, except for one thing. I never received an email. I have consulted the manual and found nothing on the questions I am about to ask. Is there any way of confirming whether an email was actually sent, or if there like a log file I can check? The server is running php4 via apache on a linux machine. Any help would be appeciated, as I have no idea what could (or could not) be happening. Thank you, Michael.

[PHP] Comparing Memory Variables
Hi Everyone,
I am having a little trouble getting a memory variable and a session variable to
compare correctly
I have an if statement as below:
if ($id=='{$SESSION["id"]}') {
echo "working";
}
ID is a memory variable that is equal to five, and the session variable id is also
equal to five.
When I do through the check again $id is set to be the characters {$SESSION["id"]}
rather than the five that it was previously assigned to.
Basically what it is doing is assigning the characters proceeding the = sign to the
variable $id rather than doing the comparison.
Does anyone know how I can get around this. I tried two = signs and the working
message does not display, but one = sign displays the message but does it also changes
the value of $id.
Has anyone got any idea how I can get around this problem?
Thanks,
Michael.
