Submitting Multiple Fields In A Form (php)

Post a Comment
I currently have a page which dynamically fills in a survey (Questions, Answers as Radio Buttons/Checkboxes) from a MySQL database. The generated HTML looks something like this :

Solution 1:

Option that is selected , will be in your $_POST array and radio2 instead of radio[2] even if yours works too, or use name radio[] in all of your radio buttons ,you will get array that contains all radio buttons that are selected.

Also , options that are checked should be in an array that is in the same $_POST array

You use a simple name for checkbox,this will only send the last value checked to your php script and will work as radio even if more than one value is checked so:

Instead of name="Check4" it must be name="Check4[]".

And for displaying answers , you can iterate over values of $_POST simply like this : 

<?phpif($_POST['submit']) {

    foreach($_POSTas$key=>$value){  
      echo"Input name : $key Value:$value";//add condition to exclude your button or hidden fields
    }
  }
 ?>

Solution 2:

Do something like this:

<formid="form1"name="form1"method="post"action="">
1 . How do you classify yourself?
<br/><inputtype="radio"id="radio[0]"value="Alien"name="question1" />Alien     
<br /><inputtype="radio"id="radio[1]"value="Hobbit"name="question1" />Hobbit     
<br /><inputtype="radio"id="radio[2]"value="Tree"name="question1" />Tree     
<br /><br/>

2 . Who are you?
<br/><inputtype="radio"id="radio[3]"value="Camel Collector"name="question2" />Camel Collector     
<br /><inputtype="radio"id="radio[4]"value="sadasd"name="question2" />sadasd     
<br /><inputtype="radio"id="radio[5]"value="Voolome"name="question2" />Voolome     
<br /><inputtype="radio"id="radio[6]"value="31231235"name="question2" />31231235     
<br /><br/>
3 . Test Question
<br/><inputtype="radio"id="radio[7]"value="Nobody Knows"name="question3" />Nobody Knows     
<br /><inputtype="radio"id="radio[8]"value="Somebody Knows"name="question3" />Somebody Knows     
<br /><inputtype="radio"id="radio[9]"value="Who Knows"name="question3" />Who Knows     
<br /><br/>
4 . Test Question 2
<br/><inputtype="radio"id="radio[10]"value="Answer1"name="question4" />Answer1     
<br /><br/>
5 . First Multiple
<br/><inputtype="checkbox"value="Bike"name="question5[]">Answer One<br><br /><inputtype="checkbox"value="Bike"name="question5[]">Answer Two<br><br /><inputtype="checkbox"value="Bike"name="question5[]">Answer Three<br><br /><br/>
6 . First Open!
<br/><inputtype="text"name="question6" /><br /><br/></form>

Solution 3:

to validate radio button use this:

if($("#radio:checked").length==0)
{
  alert("Please Select atleast one");
  returnfalse;
}
