 +This assumes you have `UID`, `id` or `GUID` in your SQL query because that value will be passed to the Edit or Delete page for determining which row to affect.  The library is smart enough to use whichever one you put in the SELECT query.  If your unique identifying column name is not one of these three, then to make the **wtkBuildDataBrowse** work properly you will need to alias it.  For example:
 +
 +<code sql>
 +SELECT `pet_id` AS `UID`, `pet_name`

 </code> </code>
  
 +==== More Buttons ====
  
 +If you want more buttons this is easily done by assigning them in the **$gloMoreButtons** PHP variable.  Similar to Edit and Delete buttons, this assumes you have `UID`, `id` or `GUID` in your SQL query because that value will be passed to the page for accessing.
 +
 +These extra buttons will be put to the between the Edit button and the Delete button.
 +
 +<code php>
 +$gloMoreButtons = array(
 +                'User Logins' => array(
 +                        'act' => '/admin/userLogins',
 +                        'img' => 'beenhere'
 +                    ),
 +                'User Updates' => array(
 +                        'act' => '/admin/userUpdates',
 +                        'img' => 'assignment'
 +                    ),
 +                'Send Invite' => array(
 +                        'act' => '/admin/sendInvite',
 +                        'img' => 'send'
 +                    ),
 +                'Send Password Reset' => array(
 +                        'act' => '/admin/sendResetPW',
 +                        'img' => 'send'
 +                    )
 +                );
 +</code>
 +
 +In the above example, the 'User Logins' will be the hover-over title on the button.  The 'act' value defines the page which will be gone to.  For example, the 'User Logins' button will go to the userLogins.php page in the /admin/ folder.  The 'img' determines the MaterializeCSS icon which will be used.  In the 'User Logins' example the generated HTML code will be:
 +
 +<code html>
 +<a onclick="JavaScript:ajaxGo('/admin/userLogins',0,7);"
 +   class="btn btn-floating btn-small"><i class="material-icons"
 +   alt="Click to User Logins" title="Click to User Logins">beenhere</i></a>
 +</code>
 +
 +Here is how these actually look on the page:
 +{{::morebuttons.png?nolink&500|}}
 +
 +
 +==== Conditional Edit and Delete ====
 +
 +If you want only some rows to have the Edit button, this can be done by defining a column and the conditional data required to be allowed to edit.
 +
 +For example, if you only wanted to allow wtkUsers with a SecurityLevel of 80 to be allowed to edit, you would add these two lines before the call to **wtkBuildDataBrowse**.
 +
 +<code php>
 +$gloEditCondCol     = 'SecurityLevel';
 +$gloEditCondition   = '80';
 +</code>
 +
 +Likewise, you can set a condition on Delete button displaying by setting the following PHP variables.
 +
 +<code php>
 +$gloDelCondCol     = 'SecurityLevel';
 +$gloDelCondition   = '90';
 +</code>
 +
 +===== Printing Mode =====
 +
 +If the page is in printing mode or the data is being exported, then the Add, Edit and Delete buttons will not be displayed.  This can be set by:
 +
 +<code php>
 +$gloPrinting = true;
 +</code>
 ===== Column Alignment ===== ===== Column Alignment =====
  
 All columns will be left justified by default.  To make a column center or right justified, just assign it in the PHP global variable like this: All columns will be left justified by default.  To make a column center or right justified, just assign it in the PHP global variable like this:

 +===== Display UID Column =====
  
-==== More Buttons ====+By default when you have your unique identifying column (UID, GUID, ID) in the SELECT statement, it will not be shown.  If you want it shown, you can simply set this variable to false.

-===== WTK Page Builder =====+===== Custom HTML Row and Header ===== 
 + 
 +Usually you want the data returned in simple columns, and that is the default for wtkBuildDataBrowse.  If you need a custom HTML layout and Header, that is easily done.  Simply define those in these two PHP variables and wtkBuildDataBrowse will replace @ColumnNames@ with the data from the associated column.  For example, from the demo/listCustomRowHTM.php page you can see this code: 
 + 
 +<code php> 
 + 
 +$pgSQL =<<<SQLVAR 
 +SELECT `UID`, DATE_FORMAT(`AddDate`, '$gloSqlDateTime') AS `Date`, 
 +    CONCAT(`FilePath`, `NewFileName`) AS `WTKIMAGE`, 
 +    CONCAT(`FirstName`, ' ', COALESCE(`LastName`,'')) AS `Name`, 
 +    `Address`, `City`, `State`, `Zipcode` 
 +  FROM `wtkUsers`

 +</td>

 + 
 +$pgHtm  = '<h4>Listing with Custom Row Template</h4>' . "\n"; 
 +$pgHtm .= wtkBuildDataBrowse($pgSQL); 
 +</code> 
 +===== wtkRowFunction ===== 
 + 
 +This feature is rarely needed but does give you amazing flexibility.  Definitely review the /demo/listRowFunction.php file to see it in action. 
 + 
 +When you need complex rules and customization of HTML based on the data of a returned row, you can use the **wtkRowFunction** function.  Before calling **wtkBuildDataBrowse** define your wtkRowFunction function and call wtkSearchReplaceRow with first parameter of '@RunFunction@'. 
 + 
 +Here is example code: 
 + 
 +<code php> 
 +// You define the next function in any way you like 
 +function wtkRowFunction($fncHtmRow, $fncData){ 
 +    $fncNewRow = $fncHtmRow; 
 +    if ($fncData['PetType'] == 'Dog'): 
 +        $fncNewRow = wtkReplace($fncNewRow, '<tr id','<tr class="deep-purple lighten-3" id'); 
 +    endif; 
 +    if ($fncData['CanTreat'] == 'CanTreatY'): 
 +        $fncNewRow = wtkReplace($fncNewRow, 'CanTreatY','<i class="material-icons green-text">pets</i>'); 
 +    else: 
 +        $fncNewRow = wtkReplace($fncNewRow, 'CanTreatN','<i class="material-icons red-text">pets</i>'); 
 +    endif; 
 +    return $fncNewRow; 
 +} 
 + 
 +$pgSQL =<<<SQLVAR 
 +SELECT p.`UID`, p.`PetName`, p.`City`, 
 +    L.`LookupDisplay` AS `PetType`, 
 +    CONCAT('CanTreat',p.`CanTreat`) AS `CanTreat`, 
 +    `fncContactIcons`(p.`OwnerEmail`,p.`OwnerPhone`,p.`Latitude`,p.`Longitude`,'Y',p.`UID`,'Y','Y','') AS `OwnerContact` 
 +  FROM `pets` p 
 +   LEFT OUTER JOIN `wtkLookups` L ON L.`LookupType` = 'PetType' AND L.`LookupValue` = p.`PetType` 
 +WHERE p.`DelDate` IS NULL 
 +SQLVAR; 
 + 
 +wtkSearchReplaceRow('@RunFunction@', ''); // second parameter not used for RunFunction 
 +// above line is what triggers wtkRowFunction to be called for every row 
 + 
 +$pgHtm .= wtkBuildDataBrowse($pgSQL); 
 +</code> 
 + 
 +Utilizing this, the wtkBuildDataBrowse function will call your **wtkRowFunction** function passing it the row of data that was retrieved and formatted.  Your function can modify the row HTML in any way and has full access to the data via the passed **$fncData[]** array.  Then you return the modified HTML which will be used in the browse list. 
 + 
 +====== Demo Pages ====== 
 + 
 +We have several demos showing all the different functionality for the **wtkBuildDataBrowse** function which you will find is one of the most useful functions in the Wizard's Toolkit library. 
 + 
 +The PHP demos have exact minimalist code examples of how easy it is to use the powerful feature of passing a SQL query to generate a full listing web page with all of the features listed above. 
 + 
 +  * /demo/listDataMin.php - uses wtkFillBrowsePage 
 +  * /demo/listCustomHTML.php - demo wtkFillBrowsePage with custom HTML template 
 +  * /demo/listSortAligns.php - uses wtkSetHeaderSort 
 +  * /demo/list3demo.php - 3 lists on one page 
 +  * /demo/listWithImage.php - demo of WTKIMAGE feature 
 +  * /demo/listRowFunction.php - demo wtkRowFunction for extreme flexibility 
 +  * /demo/listCustomRowHTM.php - demo $gloColHdr and $gloRowHtm
