Make sure your first HTML form is correctly pointing to your php script that does the checking. For example inside FORM, use METHOD = "POST" and ACTION="check.php" In your check.php, use IF to verify all the fields, like this$VALID = 1;

if ((!$A) OR (!$B) OR (!$C))$VALID = 0;

if ($VALID) print "You entered$A $B$C Thanks for completing the form. Press submit if these are correct, otherwise go back."

else print"All the fields were not entered. Please go back."

<< If all is okay u click the send button at the bottom of the page and it emails it to me >>

Then if the info is valid above, you want to supply another submit button and have it remember the values for $A,$B, $C by printing the form to the screen and using type HIDDEN INPUT TYPE='HIDDEN' name='A' value='$A'
INPUT TYPE='HIDDEN' name='B' value='$B' INPUT TYPE='HIDDEN' name='C' value='$C'

and pass in your form as METHOD = "POST" and ACTION = "submit.php" or whatever for your final submission where you use the PHP mail( ) command. That should do it. You only want to print " " the second form and submit button though if $VALID = 1 (true).

does that look correct

thanks

Yes, looks right. The "tricky" thing is you wanted a second submit button after the data was entered, so you have to pass the data a second time for $Q1 to$Q10 all as type = "HIDDEN". I believe that is how to do it, otherwise the data will not be remembered from the previous web page when you go to mail( ) it.

That is indeed correct. Once you POST data to a page, any subsequent pages will have to include the data somewhere else (session variables or form variables) in order to access them. I prefer form variables as in Phil''s method described, because it is not in any way based on the client having their cookies enabled within their browser.

The downside with form variables, is that they are not as secure as cookies in terms of data validation, so make sure that you validate the data correctly. For example, don''t let the client be able to "bust out" of your hidden fields by placing a quote in the data and then create some dangerous XSS exploit by using javascript to hijack information.

It''s a simple process, but one that is often overlooked.

AWESOME!@#! it works

thanks alot for that

now im trying to print what they people answers were

here is the code:

$VALID = 1; if ((!$Q1) OR (!$Q2) OR (!$Q3) OR (!$Q4) OR (!$Q5) OR (!$Q6) OR (!$Q7) OR (!$Q8) OR (!$Q9) OR (!$Q10))$VALID = 0;

if ($VALID){ echo( "Thanks for completing the form. Press submit if the following is correct, otherwise go back."); echo(" "); echo("Question 1:$Q1");
echo("

");
echo("Qusetion 2: $Q2"); echo(" "); echo("Question 3:$Q3");
echo("

");
echo("Question 4: $Q4"); echo(" "); echo("Question 5:$Q5");
echo("

");
echo("Question 6: $Q6"); echo(" "); echo("Question 7:$Q7");
echo("

");
echo("Question 8: $Q8"); echo(" "); echo("Question 9:$Q9");
echo("

");
echo("Question 10: $Q10""); } else{ echo("All the fields were not entered. Please go back."); } ?> </body> </html> now it says "Parse error: parse error in /www/virtual/calebt.recoil.net.nz/htdocs/others/check.php on line 38" which is the else { line what is wrong there? where it has echo(" ") there is a < p > in there [edited by - cza on August 13, 2003 10:06:55 PM] #### Share this post ##### Link to post ##### Share on other sites << echo("Question 10:$Q10""); >>

You have a second quote mark after the 10.

<< Parse error: parse error which is the else { line >>

Yeah, I think its the second " mark. Also, after your last echo, you want to echo " " again a new form and submit button, passing the variables $Q1 to$Q10 all as type hidden to have them "remembered" for your mail( ). Another point: you can use simply -br- (with < > for new line in HTML) at the end, you don't have to echo" " again.

PHP is easy to learn and works well. I use it for my brother's mortgage business. PHP.net is the official site for documentation. Plenty of tips on the language and discussion there.

sweet will try now

thanks alot for help pillvaz

 i have encountered another problem when im echoing the results since they are radio buttons the answers to them are "on"

this is what happens when all fields are filled out:

Question 1: on

Qusetion 2: on

Question 3: on

Question 4: on

how do i change the on to the answer they are given

e.g.

Question 1

Female ()

then on the next page instead of showing
Question 1 on

it shows

Question 1 : Male

<< Question 4: on how do i change the on to yes ?? >>

Use Google dude, that's what I use for questions.

You use this in your HTML form

And when that radio is selected the variable $Q1 is whatever. Normally only one radio button can be selected in a group, so if you want to do a multiple selection thing, use check boxes instead input type="checkbox" name="Q1" value="whoever" And like magic, your variable$Q1 will take on the value whoever when checked.
