More on CheckBox & PHP
|Do note that the "serial number" (variable n) you assign in the form needs to be sequential in the order the page gets rendered. I.e. when you read your lines of code from the top down, the variable n you assign to each checkbox should be sequential. This only comes into play if you have your checkboxes in a table with more than one column. Your displayed data might go down one column and then down the next, your variable n needs to go left to right, row by row.|
|All your check boxes have the same name. when So when php inserts form values into mysql, I need each box to have a separate name. but only 3 can be checked, I am inserting 9 check boxes. check is not like radio with same name. |
|Thanks, This code is effective for my work.|
|Thanx a lot......|
|The demo works very nice, but when I copy and paste the complete code and save as test.html the form is there but does not check how many boxes are checked. Why? thanks.|
|Richard,, same problem !|
|Now it is rectified. There was two single quotes on onClick event. Sorry. Try now. |
|Hi, Thanks for the tutorial it was very helpful. I was wondering if that could be converted for text fields? In my form there are 3 text fields but I want the visitor to insert a number in only 1 text field. Would be grateful for your advise, thanks.|
|plz tell me how to uncheck boxes using forloops /......... I have 18 checkboxes , aLL are checked yes by default when u click on the boxes unchecked then you have to print the numbers side by side in alert ..|
|You can little modify the script on Checkbox array and do this. Let us know if it works.|
|i want same functionality for asp.net checkbox|
|Is there a modification to this that allows each checkbox to have a unique value and the user cannot exceed a set sum of these values? |
ie. checkbox value=1, checkbox value=.5, checkbox value=1.5, checkbox value=2, sum of boxes checked not to exceed 3.
|Good point. This modification is added with a demo. |
|Ya good examples. I was very useful for me to use in my codes. |
|My form feeds a database where each checkbox has it's own lengthy name. The checkboxes are also inside of different table names as they correspond to the database. Really, I just need to limit the entire number of checkboxes checked on the form to be no more than 25. Having trouble getting anything I've tried to work. Can you help?|
|There is an option in Firefox in the pop up message saying:|
"Prevent this page from creating additional dialogs" as soon as you tick this box, this script becomes inactive and you can check all the boxes! That is what I consider a bug!
|That is a protection given by browser, so script can't prevent or stop that. |
This is not a bug .
