I am continuing my attempt to port an established web site with mysql backend to an intranet site.  To date I have established the database and web site, with tables and data, on a stand-alone Windows 7/Wamp setup.

The intranet web site functions correctly.  I can access the database from phpmyadmin however, when I attempt to use the intranet form (php/html) to access the database I am getting an "Undefined index" error returned.

I have made several corrections based on the "Experts" feedback.  I now need some additional assistance


Specifics:

      Internet:      MySQL 5.0, PHP 5, Apache on Linux Server

      Intranet:      MySQL 5.0.7, PHP 5.3.5, Apache 2.2.17, on Windows 7


Error:

      Notice: Undefined index: eMail in C:\wamp\www\part\edit_pprq1.php on line 62

      Notice: Undefined index: Dateother1 in C:\wamp\www\part\edit_pprq1.php
                                 on line 216

      Notice: Use of undefined constant FirstAidTrainingOther -  
                                   assumed 'FirstAidTrainingOther' in
                                   C:\wamp\www\part\edit_pprq1.php on line 262

Code:

      62.      <p><font size="2" face="Arial">4.&nbsp; Occupation:<input        
                                            type="text" name="Occ" value="<?php echo $data2["Occ"]?>"
                                            size="30"> email:<input type="text" name="eMail" value="<?php
                                             echo $data2['eMail']?>" size="40"></font></p>

      216.      <td width="64"><input type="text" name="Dateother1" value="<?php
                                            echo $data2["Dateother1"]?>" size="8"></td>      

      262.      <p><font size="2" face="Arial">16. First Aid Training;     Red Cross
                                            Advance:<input type="checkbox" name="FirstAidTrainingRCA" <?
                                             php if ($data2['FirstAidTrainingRCA']=="ON"){echo "checked";}?
                                             >>&nbsp;&nbsp;&nbsp; CPR:<input type="checkbox"
                                             name="FirstAidTrainingCPR" <?php if       ($data2['FirstAidTrainingCPR']
                                              =="ON"){echo "checked";}?>>&nbsp;&nbsp;&nbsp; EMT:<input       
                             type="checkbox" name="FirstAidTrainingEMT" <?php if ($data2
                                            ['FirstAidTrainingEMT']=="ON"){echo "checked";}?
                                            >>&nbsp;&nbsp;&nbsp;Other:<input type="text"
                                               name="FirstAidTrainingOther" value="<?php echo $data2
                                             ['FirstAidTrainingOther']?>" size="20"></font></p>

These first two are warnings, which tell you the used array items doesn't exist.
One option is to declare them before use
if (!isset($data2['Occ'])) $data2['Occ'] = '';
if (!isset($data2['Dateother1'])) $data2['Dateother1'] = '';

Open in new window

Another is to check everytime when used
<p><font size="2" face="Arial">4.&nbsp;
Occupation:<input type="text" name="Occ" value="<?php if (isset($data2['Occ'])) echo $data2["Occ"]; ?>" size="30">
email:<input type="text" name="eMail" value="<?php if (isset($data2['eMail'])) echo $data2['eMail']; ?>" size="40">
</font></p>

Open in new window


The third warning tells you, you used a constant instead of a string as Dave told you in #27309891 before, but it seems to be already fixed in your code. Please use code tags to avoid strange line feeds in this posting.

acbxyz,

Does "array items doesn't exist" mean that:

    1.  The field does not exist
or
     2. The field is empty

Your first, if you assign null to an array field you won't get this error.
To check it, you can use array_key_exists(), while isset returns false if the value of a field is null.
http://php.net/manual/en/function.array-key-exists.php
Everythime, this function returns false you get an error if you want to use it.
