help with radio button

[Lassie]

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.

 

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 */

            while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
                
               $coverID=$row['coverID'];
                echo"<img src=\"/wordpress_3/wp-content/plugins/Authors2/jackets/{$row['pix']}\" />";
                echo"<td>";
                echo $coverID;
                echo "<Input type = 'Radio' Name ='cover' value= '$coverID'/>";
                ?>
                </tr></table>
                <input type=submit value=submit>
                </form><?php
                }
          }

I have now got the form to submit with a vale but I can only get one button(out of a test of 3) to work.

Just to emblish this post the link goes to the following code.

The idea is to pass the cover id to the finished cover function which will display the selected cover with other data.

The $_GET['coverID'] just gives me $coverID. not the ID value which is numeric.

 

//output page content for each plugin submenu page
    if ($_GET['page']== "submenu7"){
        $cover=$_GET['coverID'];
        echo $_GET['coverID'];
        FinnishedCover($cover);
    }elseif($_GET['page'] == "submenu6") {
        AuthorRegistration_page();
    } elseif ($_GET['page'] == "submenu5") {
        cover();
    } elseif ($_GET['page'] == "submenu4") {
        Upload_page();
    } elseif ($_GET['page'] == "submenu3") {
        Marketing_page();
    } elseif ($_GET['page'] == "submenu2") {
        Synopsis_page();
    } else { //page 1 is default
        General_page();
    }

Sounds like you've enclosed a variable in a single quoted string. Post the code that generates that part of the form.

Hi Thanks

This is the code

echo $coverID gives the correct value(although only one radio button works

but that is not passed in the link.

//process selection of cover
            if (isset($_POST['cover'])) {
                $coverID=$_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";
            }

You aren't even within <?php ?> tags where that variable is, so there's no way it will echo the value of it. Didn't you say in the OP that the problem was with a radio button? That code doesn't produce one . . .

 

<ul><li class="demo-menu-link"><a href="?page=submenu7&coverID=<?php echo urlencode($coverID); ?>">Finished Cover</a></li></ul>

Hi Thanks.

Yes i have just discovered that and it now works. I still cant get the buttons to work though. Only the first one works.

?><form action="<?php $_SERVER['PHP_SELF'] ?>" method="POST" id="cover" enctype="multipart/form-data">
            <table width="700"><tr><?php
            /* display picture and radio button */

            while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
                
               $coverID=$row['coverID'];
                echo"<img src=\"/wordpress_3/wp-content/plugins/Authors2/jackets/{$row['pix']}\" />";
                echo"<td>";
                echo "<input type = 'radio' name ='cover' value= '$coverID'/>";
                ?>
                <input type="submit" value="submit">
                </tr></table>
                
                </form><?php
                }

[Pikachu2000]

Can you explain what about it doesn't work, please?

[Lassie]

Sorry. Only one button is active.Three images show each with a radio button and a submit button, but only the first one will process the form whem the radio button is checked and the submit button pressed.

Post the result of a View--->Source that includes the html markup for the form.
