[PHP] check box help.
Hey gang I'm using a checkbox in a form that has its values dumped into a mysql database. for some odd reason, the checkbox information is lost It worked earlier so I'm guessing I introduced a typo someplace. this is the code in the form. I figure if this looks ok to you all. I just need to go search through my code more carefully. H2 Recurring Seminar:input type=\checkbox\ name=\recur\ value=\$recur\/H2 Recurring seminars are displayed with a different color text in listings BR I create the form as a variable that is displayed. thanks, chris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP] PHP_SELF
Michael,
I've got a program set up like you describe.
the problem is I've noticed that my variables are NOT stable
this is it in a nutshell
1) show 3 options with radio buttons for each
2) based on above query a database and show a list of the records
(now it just dawned on my that I've been doing this with URL's and that might be the
problem)
3) show all of the fields in the record to edit as necessary.
4) update the table
1,2,3 work fine. I save the id number of the record. however, it isn't persistent.
IOW,
suddenly the variable is set to null.
am I just not understanding how php scripts work?
or is my usage of URL's in appropriate. I'm new to the world of php.
thanks
chris

I do this sort of thing all the time. The format I use typically
follows this logic.
The PHP file has four IF-ELSEIF-ELSE sections.
pg=1 or blank is the initial form
pg=2 is the error check looking at input values.
If it passes, pg is set to 3.
If not, set to 1. The advantage of this is the original input
values can be saved and displayed with Value=? ECHO..? sequences so
the use doesn't have to input everything if they make a mistake. The
error can be highlighted with a color or text!!!.
pg=3 shows a visual verification page. The user can scan the input
and use the back button to make changes or click OK to proceed.
pg=4 is the action step - send an e-mail including the input, post
input to a database or ???
The sections are written in this order - 2, 4, 3, 1.
IF($pg=2)
{ do the error checking
e.g., if fields A, B, and C are not blank = OK
e.g., if a value is 100 = not OK
IF OK, $pg=3; IF not OK, $pg=1;
}
ELSEIF($pg=4)
{ do the action stuff.
}
ELSEIF($pg=3)
{ show an html page in a nice format showing the input values
IF they like it, the form submit button sets pg=4, and
uses hidden fields to copy all of the input values to pg 4.
}
ELSE
{ Show the initial input form.
use INPUT TYPE=HIDDEN NAME=pg VALUE=2
}
The form can include error check and input tags like this:
? IF(($pg=1) and ($val3==))
{ ECHOFONT COLOR=REDRequired./FONTBR; } ?
TEXTAREA WRAP=SOFT NAME=val3 COLS=50 ROWS=5? ECHO
$val3;
?/TEXTAREA
INPUT TYPE=RADIO NAME=v2 VALUE=6 ?IF($v2==6) { ECHO
CHECKED; } ? 6
INPUT TYPE=RADIO NAME=v2 VALUE=7 ?IF($v2==7) { ECHO
CHECKED; } ? 7
and so on. Hope this is useful...
Im trying to introduce some logic into a form.I am unsing $PHP_SELF
as the target.
form action=\$PHP_SELF\ method=\POST\ type=\multipart/form-data\
I have a text area that the user inputs their age. What I want is
that if the field is blank, to stop the script and send the user
back to fill in their age. My problem now is that if I go to the
blank application form, The script interprets the form as being
blank and spits out the error. Ideal scenario, a blank form is
presented to the user, and when the form is submitted, do the logic
check and act accordingly. Is it possible using $PHP_SELF as the
target, or do I have to use 2 files: a form 'front end' with the php
logic in the 'backend'??
if ($Age = ) {
echo Please go back and enter your age.; } exit();
Thanks

Now here is what happens. On a first time view of the page it outputs
'NO' (Good). If I dont enter anything in the age field and submit the
form it outputs 'NO' (Good). If I enter a value into the age field and
submit, it outputs 'NO' (Not Good).
You are assigning these values, not comparing them
$post = 1// puts 1 in the variable $post
$post == 1 // compares $post to 1
you need to change your code to
if ($post == 1 $age == ) { blah blah blah

[PHP] Script FLOW-- branching and subroutines/functions
Hello all.
I'm relatively new to the world of PHP, but I've programmed in C, C++, Rexx, in the
past.
What I'm working on is this and I wanted to clarify some things about how PHP "runs"
I've got a function that contains a form and depending on the entry to the form, which
is
then checked against a database(to avoid duplicates in the list). once a non
duplicate
is determined it advances to the next form for data entry. I had the whole thing in a
while
loop but that was a disaster.
I pass $PHP_SELF to the functions, am I to understand that once the script returns
from
the function it starts executing at the beginning?
While( Not stopping)
{
do first form()
check against database()
if(above check is OK)
do the information form()
if(form entered)
put data into database()
}
as it is structured above it just runs and runs through the first form.
I put a break into the while loop, but the script still seems to run right to the end.
I suppose to phrase another way.
how do I do this
call form
wait there until it is completed
call check
look for duplicate
then if ok
I then commit to database after entereing data
PHP doesn't seem to stop execution and wait for user input. it seems to merrily plug
away.
thanks for any input gang,
Chris

Re: [PHP] Script FLOW-- branching and subroutines/functions
Thanks, Michael
You've reinforced how I've come learn that php does things. When I first tried the
script
it simply printed the first form over and over. it was kind of funny in a way. I'll
restructure
my program now to account for how PHP does things. thanks again,

Re: [PHP] Simple PHP 4 and MySQL question about query
To follow on, one thing this newbie learned is that it is usually best
to build the query string and then pass it to the mysql_query funcion.

What mysql_funtion should I use to echo the result and with what

Regards,

If id is an integer type field, you will not get a result using the query
you show. Remove the single quotes around $id as they indicate a text
type value. Also you shouldn't need single quotes around islname - so
your query might look more like:
$result = mysql_query("SELECT islname FROM $table WHERE id=$id");
Then you can use mysql_fetch_array to get row[s] containing an array of
all the fields (one!) in your query, and then use extract to put the
field values in a variable named as the field. (The example for
mysql_fetch_array shows another way of displaying the fetched values.)
So:
$row = mysql_fetch_array($result);
extract($row);
echo $islname;
