Question

i’m new to php , i have been searching for a tutorial regarding inserting form’s input(text) , radio and selection data to MySQL database’s table using php. i found some tutorials but most are confusing. So i decided to ask.

Okay here’s what i want to do. I have a form which have two types of input and a selection
1. input type text
2. input type radio
3. selection

Here’s the HTML code :

<form action="" method="post" enctype="multipart/form-data">

  <strong>Your Name: </strong><br>
     <input type="text" name="myname" value="" />
  <br /><br/>    

  <strong>Which class type you want:</strong><br>
    <select name="selection">
      <option value="A">A</option>
      <option value="B">B</option>
      <option value="C">C</option>
    </select>

  <strong>Do you agree?</strong><br>
    <input type="radio" name="agree" value="Yes"> or 
    <input type="radio" name="agree" value="No">


  <input type="submit" name="submit" value="Submit">

</form>  

I have set the form action to blank because the php code will be in the same file as the HTML (it’s a php file btw)

MySQL table : info
structure :
1. name
2. class
3. agree

I want the php code to insert myname into name , selection’s selected data into class , radio selected data into agree

P/S Yes i have added a connect to database php script , i just want to know how to get the form data into mysql.

Can someone write a php code example on how can i do this?

Thanks and have a nice day . I hope i have provided enough information. Thanks again if you help.

I’ve taken it a little further here, there is still plenty more that can be done and many way’s to do it, for instance you could extend the $errors array to include a field id and then highlight the HTML form field so the user can see exactly where they went wrong.
Considering your form is fairly simple you would not need this.
@Shef’s code would certainly do the job but I thought you might be interested in some more.

    <?php
    // check the form has been submitted
    if (isset($_POST['submit'])) {
        // escape the form fields and assign them to variables
        // validate myname to ensure the user entered data
        if (isset($_POST['myname']) && $_POST['myname']!='') {
            $myname = mysql_real_escape_string($_POST['myname']);
        } else {
            // create an error variable array to store errors to display
            $errors[] = 'Please enter your name'; 
        }

        // no need to validate selection here as it alway's has a value
        $classtype = mysql_real_escape_string($_POST['selection']);

        // validate agree unless you want to add 'checked' to one of the values
        if (isset($_POST['agree']) && $_POST['agree']!='') {
            $agree = mysql_real_escape_string($_POST['agree']);
        } else {
            $errors[] = 'Please tell us if you agree?'; 
        }

        //if errors found tell the user else write and execute the query
        if ($errors) {
            $message = '<p class="error">We found a problem:</p><ul>';
            foreach($error as $msg){
                $message .= '<li>'.$msg.'</li>';
            }
            $message .= '</ul><p>Please fix the error/s to continue.</p>';
        } else {
            // write the query
            $query = "INSERT INTO table (myname, classtype, agree) VALUES ";                           
            $query .= "('$myname','$classtype','$agree')"
            // run the query
            mysql_query($query);
            $message = '<p class="sucessful">Thanks '.htmlspecialchars($myname).'. Your selection has been saved.</p>';
        }
    }

    // print the message
    // show the variables in the form field so they don't need re-input
    if ($message!='') { echo $message; }
    ?>
    <form action="" method="post" enctype="multipart/form-data">

      <strong>Your Name: </strong><br>
        <input type="text" name="myname" value="<?php echo htmlspecialchars($myname) ?>" />
      <br /><br/>    

      <strong>Which class type you want:</strong><br>
        <select name="selection">
          <option value="A"<?php if ($classtype=='A') { echo ' selected'; } ?>>A</option>
          <option value="B"<?php if ($classtype=='B') { echo ' selected'; } ?>>B</option>
          <option value="C"<?php if ($classtype=='C') { echo ' selected'; } ?>>C</option>
        </select>

      <strong>Do you agree?</strong><br>
        <input type="radio" name="agree" value="Yes"<?php if ($agree=='Yes') { echo ' checked'; } ?>> or 
        <input type="radio" name="agree" value="No"<?php if ($agree=='No') { echo ' checked'; } ?>>

      <input type="submit" name="submit" value="Submit">

    </form>
