This chapter shows how to keep the values in the input fields when the user hits the submit button.
PHP - Keep The Values in The Form
To show the values in the input fields after the user hits the submit button, we add a little PHP script inside the value attribute of the following input fields: name, email, and website. In the comment textarea field, we put the script between the <textarea> and </textarea> tags. The little script outputs the value of the $name, $email, $website, and $comment variables.
Then, we also need to show which radio button that was checked. For this, we must manipulate the checked attribute (not the value attribute for radio buttons):
Name: <input type="text" name="name" value="<?php echo
$name;?>">
E-mail: <input
type="text" name="email" value="<?php echo $email;?>">
Website: <input type="text" name="website" value="<?php
echo $website;?>">
Comment: <textarea name="comment"
rows="5" cols="40"><?php echo $comment;?></textarea>
Gender:
<input type="radio" name="gender"
<?php if (isset($gender) && $gender=="female") echo "checked";?>
value="female">Female
<input type="radio" name="gender"
<?php if
(isset($gender) && $gender=="male") echo "checked";?>
value="male">Male
