I have a the following form code:
<form method="post" action="nextpage">
<input type="radio" name="p" value="A"/>
<input type="radio" name="p" value="B"/>
<input type="radio" name="p" value="C"/>
<input type="radio" name="p" value="D"/>
</form>
The next page has to return the same form with the button checked.
this code: PHP How to keep radio button state to the next page didnt help.
<form method="post" action="nextpage.php">
<input type="radio" <?php if(isset($_POST['p'])) && $_POST['p'] == 'A') echo 'checked="checked" ';?> name="p" value="A"/>
//and so on for the rest....
You need to use the below code:
<form method="post" action="nextpage">
<input type="radio" name="p" value="A" <?php if(isset($_REQUEST['p']) && $_REQUEST['p'] == "A") echo 'checked="checked"'; ?>/>
<input type="radio" name="p" value="B" <?php if(isset($_REQUEST['p']) && $_REQUEST['p'] == "B") echo 'checked="checked"'; ?>/>
<input type="radio" name="p" value="C" <?php if(isset($_REQUEST['p']) && $_REQUEST['p'] == "C") echo 'checked="checked"'; ?>/>
<input type="radio" name="p" value="D" <?php if(isset($_REQUEST['p']) && $_REQUEST['p'] == "D") echo 'checked="checked"'; ?>/>
</form>
on the next page right above code.
As in your example answer there is radio button with the name q and in your code name is p that is different in both code. Hope this will be your problem.
<input type="radio" <?=(isset($_REQUEST['p']) && $_REQUEST['p'] == 'A') ? 'checked="checked" ' : ''?> name="p" value="A" />
