    Ch 4 'Confused With Pear Error "Deprecated" '

    in PHP 5 Advanced: Visual QuickPro Guide (2nd Edition)

    Posted

    I loaded PEAR successfully and loaded the the required packages but when I run login.php I get

     

    "Deprecated: Assigning the return value of new by reference is deprecated in C:\wamp\bin\php\php5.4.3\pear\Auth.php on line 469"

     

    and a

     

    "Strict standards: Non-static method DB::isConnection() should not be called statically, assuming $this from incompatible context in C:\wamp\bin\php\php5.4.3\pear\Auth\Container\DB.php on line 150"

     

    error.

     

    Would you be able to explain this pls?

     

    I am on a win7 system and a WAMP server.

    Hi Sam. 

    this link takes me to 

    PHP 6 and MySQL 5 for Dynamic Web Sites: Visual QuickPro Guide (3rd Edition)

     

     

     

    Regarding the problem I have. 

    What i have done to try and debug is copied the style.css file into my includes file (as directed by the file structure in the book pg 54) and into a style folder that I created as the code directs

     

    <?

     

     

    <head>
      <title><?php echo $page_title; ?></title>
      <link rel="stylesheet" type="text/css" href="style/style.css" title="style" />
    </head>

     

    ?>

     

    and still the css is not loading.

     

    I have gone back to 'PHP and MySQL for dynamic websites' book and also went through my working examples and that too has led me nowhere.

     

    What I have now done is gone to the website 'www.HTML5webtemplates.co.uk', downloaded another template and that HAS WORKED fine.

     

    So I assume that there is something wrong with the CSS file in the .zip file that I downloaded?

     

    <_< 

    pls advise

    Php And Jquery

    How would one pass a php variable to a jQuery function.

     

    I would like to use jQuery to only show the delete and edit links if $_POST['user_id'] =1.

     

     

    // Table header:
    echo '<table align="center" cellspacing="0" cellpadding="5" width="75%">
    <tr>
    <td align="left"><b>Edit</b></td>
    <td align="left"><b>Delete</b></td>
    <td align="left"><b><a href="view_users.php?sort=ln">Last Name</a></b></td>
    <td align="left"><b><a href="view_users.php?sort=fn">First Name</a></b></td>
    <td align="left"><b><a href="view_users.php?sort=rd">Date Registered</a></b></td>
    </tr>
    ';
     
    // Fetch and print all the records....
    $bg = '#eeeeee'; 
    while ($row = mysqli_fetch_array($r, MYSQLI_ASSOC)) {
    $bg = ($bg=='#eeeeee' ? '#ffffff' : '#eeeeee');
    echo '<tr bgcolor="' . $bg . '">
    <td align="left"><a href="edit_user.php?id=' . $row['user_id'] . '">Edit</a></td>
    <td align="left"><a href="delete_user.php?id=' . $row['user_id'] . '">Delete</a></td>
    <td align="left">' . $row['last_name'] . '</td>
    <td align="left">' . $row['first_name'] . '</td>
    <td align="left">' . $row['dr'] . '</td>
    </tr>
    ';
    } // End of WHILE loop.
     
    echo '</table>';

    My form loads ok. login.php

     

    everything works like it should EXCEPT that when I submit the form with no password value I get the followoing error:

     

    Notice: Undefined variable: p in C:\EasyPHP\www\basicMySql\includes\login_functions.inc.php on line 41

     

    But if i fill in a value, even a false one, the code works fine. 

     

    could it be something to do with my isset()/empty() function?

    Ch 12 Understanding 'List()'

    list ($check, $data) = check_login ($dbc, $_POST['email'], $_POST['pass']);
     
    Regarding the above.
     
    would you be able to go into a bit more detail. Another thing ...
     
    PHP.net states  that it is not really a function  :blink:

     

    "Like array(), this is not really a function, but a language construct. list() is used to assign a list of variables in one operation." - php.net

    I am not getting the desired results from the login lesson :

     

    Cookies and Sessions page  375

     

    when i try and run

     http://127.0.0.1/basicMySql/includes/login_page.inc.php

     

    I get the form, which I  complete BUT when I submit it I get taken to a 

     

    http://127.0.0.1/basicMySql/includes/login.php

     

    which I have deleted from my directory(I am redoing this chapter which I did not get right the first time around).

     

    Would this be a cache problem?
