passing check box value to next page

nasirmunir · April 28th, 2009, 09:30 PM

I am trying to pass values from a check box to the next page, which is an insert page that is storing values for the check box field ( archive: yes if checked and no if unchecked, or 1 and 0).
Can I get some help here?

one.php:

Code:

<input type="checkbox" name="archive" value="<?=value from database ;if(value from database ==1){echo checked};" >

Something on these lines, and then on page two.php I can get values by POST and then store that in the database.

Problem is how to store uncheck value and also how to retrieve and pass value to the checkbox. A user should be able to check and uncheck if he/she wants to edit a record.

In my few failed attempts, I have been able to (to some extent) to store value as "1" for checked box, but am struggling to store value for unchecked and then retrieving the stored value for editting.

Any help would be appreciated,
Thanks

Code:

<input type="checkbox" name="archive" value="<?if(value " from database==1) "echo checked";else echo "unchecked";?> <?if(value from database==1) "echo checked";?>

if database value is one then checkbox will be checked.and you could read the value from $_POST['archive'].

Thanks for your help, but I am still struggling.
I can see the values inserted in the database as 1 and 0, if the checkbox is checked or unchecked respectively.
I can also see the values retrieved from the database as 1 or 0 when I go to edit page again.
The problem is: based on the values it is not checking or unchecking the box for values retrieved from the database.
How can check the box if the value is 1 and uncheck otherwise. I have tried using 'checked' outside of value attribute, it works but then it is checked for every value.
Any clue ?

Code:

<input type="checkbox" name="archive" value="<? if($p['archive']==1) print 'checked'; else print 'unchecked'?>" ><?=$p['archive']?></input>

The source code of page for uncheck is:

Code:

<input type="checkbox" name="archive" value="unchecked" />0

and the source code of page for check is:

Code:

<input type="checkbox" name="archive" value="checked" />1

Hi,

To set a checkbox as ticked, you should use the checked attribute. It doesn't matter what you set checked to, it just has to be present, but the normal way to do it is:

Code:

<input type="checkbox" name="archive" checked="checked" />

Just change your code to add this if archive is 1.:

Code:

<input type="checkbox" name="archive"
 <?php if($p['archive']==1) print 'checked="checked"'; ?> />

you should use "checked" to make a check box checked.
the source code must look like this.
To check:

Code:

<input type="checkbox" name="archive" value="checked" checked>1

To uncheck:

Code:

<input type="checkbox" name="archive" value="unchecked">0

add print statements to print "checked" at the end of tag
