PHP undeclared variables error -


my code , form:

<?php include("includes/connect.php"); $content = "select * content content_page='home'"; $result = mysql_query($content); $row = mysql_fetch_array($result); ?> <form method="post" action="admin_home.php"> headline:</br> <input type="text" name="content_title" value="<?php echo "$row[content_title]" ?>"></br>   </br> main content:</br> <textarea type="text" class="txtinput" cols="55" rows="20" name="content_text"><?php echo   "$row[content_text]" ?></textarea></br></br> <input type="submit" name="submit" value="save changes"> </form>

code want happen when 'submit' button pressed:

<?php   include("includes/connect.php"); if(isset($_post['submit'])){   $order = "update content            set content_title='$content_title', content_text='$content_text' content_page='home'"; mysql_query($order);  }

?>

the error get:

notice: undefined variable: content_title in /applications/xampp/xamppfiles/htdocs/templacreations/admin/admin_home.php on line 63  notice: undefined variable: content_text in /applications/xampp/xamppfiles/htdocs/templacreations/admin/admin_home.php on line 63

line 63 following line submit button code:

set content_title='$content_title', content_text='$content_text'

is not declaring them?

it looks looking post values of form.

they not contained in variables $content_title , $content_text. in fact error telling you haven't assigned variables.

they contained in $_post array value of submit.

i.e

<?php   include("includes/connect.php"); if(isset($_post['submit'])){    //sanitize data , assign value variable    $content_title = mysql_real_escape_string($_post['content_title']);    $content_text = mysql_real_escape_string($_post['content_text']);    $order = "update content              set content_title='$content_title', content_text='$content_text'              content_page='home'";   mysql_query($order);  }  ?>
