Question

Here’s the form handling

if(isset($_POST['clear'])) {
    mysql_query("DELETE FROM md5dictionary");
}

if(isset($_POST['submit'])) {
    if(strlen($_POST['keywords']) < 1 || ctype_space($_POST['keywords']) == true) {
        $errors['blank'] = "<span class='error'> Please insert a word </span>";
    } else {
        $newword = $_POST['keywords'];
        $db_checkExist = mysql_query('SELECT * FROM md5dictionary WHERE keywords="' . $newword . '"');
        echo mysql_num_rows($db_checkExist) . "<br />";
        if(mysql_num_rows($db_checkExist) > 0) {
            echo "outside else " . mysql_num_rows($db_checkExist);
            $finalResult = "<span class='error'> Failed!!! </span>";
        } else {
            echo "inside else " . mysql_num_rows($db_checkExist);
            $md51 = md5($newword);
            $md52 = md5($md51);
            mysql_query('INSERT INTO md5dictionary(keywords, mdFive, mdFive2) VALUES ("' . $newword . '", "' . $md51 . '", "' . $md52 . '")');
            $finalResult = "<span class='success'> Thank you! Wanna add another one? </span>";
        }
    }
}

Here’s the form

<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post">
    <fieldset> Input Form </fieldset>
    <label for="keywords"> Input new Keywords into dictionary: </label>
     <?php echo $finalResult; ?>
     <?php echo $errors['blank']; ?>
        <input name="keywords" type="text" />
        <input name="submit" type="submit" value="Add!!" />
        <input name="clear" type="submit" value="Clear Database" />
</form>
<h1> Datas: </h1>
<?php
    $result = mysql_query("SELECT * FROM md5dictionary");
    $rows = mysql_num_rows($result);
    for ($i = 0; $i < $rows; ++$i) {
        echo "Data " . $i . "<br />";
        echo "keywords: " . mysql_result($result, $i, "keywords") . "<br />";
        echo "md5: " . mysql_result($result, $i, "mdFive") . "<br />";
        echo "md5_2: " . mysql_result($result, $i, "mdFive2") . "<br />";
    }
?>

Question: Why it keeps saying “Failed!” Why it has successfully insert information into my database?
There should be no spelling mistake

I know it will be time-consuming go through my dumb question but plss, i can’t explain it myself!!

Answer 1

I’m not sure about what you mean when you say it inserts and it gives “fail”.
Do you actually mean “INSERT INTO md5dictionary…” is executed, AND you have the ” Failed!!! ” code showing?

If this is so, I recommend you investiguate and revise your form flows since it is most probable that calling itself, the form tries to run twice, the second time having null values.

This is what I coming up with.

Have a good day,
