PHP - Validating Radio Button Helpp!!

I have a function to display some images and allow a user to select a choice via a radio button.The value is then passed to another function.
I have 2 problems
My selection is not being passed back and I cant assign the value to a query sring in a link to another page.
On the form do i need to add checked?
Any help appreciated.

Code: [Select]
function cover() {

            echo'<h2>Please upload your book cover or choose one from the selection</h2>
                <p>All book ideas require a cover. Your choice can be changed at a later date.</p>';


            //process selection of cover
            if (isset($_POST['submit'])) {
                $coverID=$_POST['cover'];
                echo $coverID;
                 ?> &nbsp

                <ul><li class="demo-menu-link"><a href="?page=submenu7&coverID=$coverID">Finnished Cover</a></li></ul><?php
                exit();
            }
            else{
                echo "not Submitted";
            }


            global $wpdb;
            $query = "select * from wp_cover";
            $result = mysql_query($query) or trigger_error("Query: $query\n<br />MySQL Error: " . mysql_error());
            echo mysql_error();

            if (!$result){
                return false;
            }
            
            echo'<div class="wrap"><p>choose from one of the covers below</p></div>';

            ?><form action="<?php $_SERVER['PHP_SELF'] ?>" method="POST" id="cover" enctype="multipart/form-data">
            <table><tr><?php
            /* display picture and radio button */

Hello,
I had 3 radio buttons with the same name, well, I had created 3 text box that are next to those 3 radio buttons.
When I click save to the form, I need to know which radio button had been pressed, so that I can detect & retrieve its value.
Any help?
Thanks

Hi,

I have 2 radio button's within a table and need to pass this array.

All other rows within my table can be sent as array's and captured using $_POST['field_name'][$ROW 1 value etc].

However for radio buttons this doesn't work.

As an example, a standard textbox I can send an array using the following:

 echo "<td width='33%'><input type='Textbox' width='100%' id='test' name='test[]' value='" .$row['test']. "'></td>";
 
I can then capture it using:

$test = $_POST['test'][$iLine];

This works, no problem, however for radio buttons, I can't use a static array name, as presumably it dumps all rows into the array, if I do this, only the last row has a checked button, hence I need to use the following (where $checked includes the logic to decide whether the button should be checked or not, this works correctly):

echo "<input type='radio' name='".$row['venue_id']."[]' value='1'".$checked."/>P1"
echo "<input type='radio' name='".$row['venue_id']."[]' value='0'".$checked2." />P2";

I tried using the following:

var_dump($_POST[$row]['game_id'][$iLine]);

But this just returns a null value.

Any ideas?

I have a group of 4 radio buttons. my mysql database knows which one the user selected previously when they stored some information. I now wish to display the same buttons but have radio button checked that the user chose before. I know this can be done but having one of those mind melt moments where I cannot think of the solution

so I have 4 buttons that look like this

Code: [Select]
        <input type="radio" name="clarity" id="clarity" value="Opaque">
      Opaque<br>
      <input type="radio" name="clarity" id="clarity" value="Deep">
      Deep<br>
      <input type="radio" name="clarity" id="clarity" value="Mid">
      Mid<br>
      <input type="radio" name="clarity" id="clarity" value="Pale">
      Pale<br></td>

I just need to attached a checked field to the correct item

Good Day,

I juz like to know if there any other alternative way for the code below, coz i can't update my form when i use this method for radio the button. It's not passing the value.

Code: [Select]

Edit.php

  <tr>
            <td height="36" align="center" valign="middle" bgcolor="#990000"><div align="left" class="style4">Destroy :</div></td>
            <td align="center" valign="middle" bgcolor="#990000"><div align="left">
              <label>
              <input type=radio name=destroyR value="Yes" <?php echo ($rows['destroy']=='Yes') ?'checked="checked"':''; ?> />Yes</label>
             
              <label>
              <input type=radio name=destroyR value="No" <?php echo ($rows['destroy']=='No') ?'checked="checked"':''; ?> />No</span></label>
             </div></td>
          </tr>

how do you make it so that a radio button is either checked or unchecked based on database?

i would like to display the value of the selected radio button on the same page... what i want is just reload the page and if there is a radio button selected displays it but i cant display it

<?PHP

if (isset($_GET["submit"])) {
echo $_GET["myradio"];
}

?>

<html>
<head>
</head>
<body>
<form action="<?PHP $_SERVER["PHP_SELF"]; ?>" method="get">
One <input type="radio" name="myradio" value="one">
Two <input type="radio" name="myradio" value="two">
<a href="<?PHP $_SERVER["PHP_SELF"]; ?>" name="submit">test </a>

</form>
</body>
</html>



please help guys...thanks

I am trying to make a set of radio buttons that when you make a selection, it displays a sorted database from MYSQL.  I have the MYSQL part figured out but I cannot figure out how to properly display it.

I have the following code and I made a select screen just to test:

index.html
<html>
<body>

<form action="select.php" method="post">

<input type="radio" name="table" value="table1"> Table 1
<br>
<br>

<input type="radio" name="table" value="table2">Table 2
<br>
<br>

<input type="radio" name="table" value="table3">Table 3
<br>
<br>

<input type="radio" name="table" value="table4">Table 4
<br>
<br>

<input type="radio" name="table" value="table5">Table 5
<br>
<br>

<input type="Submit" Name = "submit" value="Submit">
<input type="Reset" value="Reset">

</form>
</body></html>


select.php
<?PHP

$selected_radio = $_POST["table"];

if ($selected_radio = = 'table1) {
echo "Table 1 Here.";
}
else if ($selected_radio = = 'table2') {
echo "Table 2 Here.";
}
else if ($selected_radio = = 'table3') {
echo "Table 3 Here.";
}
else if ($selected_radio = = 'table4') {
echo "Table 4 Here.";
}
else if ($selected_radio = = 'table5') {
echo "Table 5 Here.";
}

?>
These are two separate files.  When I go to run the code, no matter what I pick, the next page is always blank.  Again, the select.php is just suppose to be a check, the real code will display the table instead of echoing a message.

I have page with male female radio button

Here's the code

Code: [Select]
$qry=mysql_query("SELECT * FROM reg_table where id=$id ");

$res=mysql_fetch_array($qry);

$radio = $res['gender'];

switch($radio)
{
   case "male":
   $mal = "checked";
   break;
   case "female":
   $fem = "checked";
   break;
}
Code: [Select]
Gender: <br />
<input type="radio" name="colour" value="male" checked="<?php $mal; ?>" />Male
<input type="radio" name="colour" value="female" checked="<?php $fem; ?>" />Female


Whats the use of checked in
<input type="radio" name="colour" value="male" checked="<?php $mal; ?>" />

Hello,

I have a simple PHP form that sends the results as a message to my email address. The form is composed only of text areas and text fields. All works well until I try to introduce radio buttons. When I get the message the result is blank. This is the form:

<form id="contact-form" name="contact-form" method="post" action="submit.php">
  <table width="100%" border="0" cellspacing="0" cellpadding="5">

      <td id="errOffset">&nbsp;</td>
    </tr>
    
    <tr>

These are the 2 files I've been updating. I'm definitely not good at PHP so any help cracking this problem would be welcome.

Thank you.

When I display the data in my database I have included a radio button in each row. When the button is clicked, the intention is to delete all the information in that row. But it won't delete anything...

?>When I add or update any information it works fine. It just won't delete anything where the radio button is clicked.
Any help appreciated! Thanks.

It seems to only wanting to tick the enabled radio button even if the row value is 1 for disabled in the database.


<?php 
             while ( $row = mysqli_fetch_array ( $result, MYSQL_ASSOC ) ) {
                  echo '
                  <tr>
           <td>' . $row['fullname'] . '</td>
                      <td style="text-align:center;"><input type="radio" value="0" name="' . $row['fullname'] . '" class="status"'; 
                      if($enabled == 0)
                      echo ' checked="checked"';
                      echo '/>Enabled';
            ?>
            <?php echo '<input type="radio" value="1" name="' . $row['fullname'] . '" class="status"'; 
                  if($enabled == 1)
                  echo ' checked="checked"';  
                  echo ' />Disabled</td>
       </tr>';
                }
            ?>
