TYPO3：选择count（*），其中包含隐藏的行

Question

我使用此代码显示我在页面ID 68的tt_address中拥有的寄存器数，并且工作正常，但它不显示隐藏的元素。

# Default PAGE object:
page = PAGE
page{
  20 = CONTENT
  20 {
    table = tt_address

    select{
      selectFields = count(uid) AS count
      pidInList = 68
      where = deleted = 0
    }

    renderObj = COA
    renderObj {
      10 = TEXT
      10 {
        value = Status: {field:count}
        insertData = 1
      }
    }
  }
}

我又如何计算隐藏的记录？

Answer 1

我认为不可能使用错字来获取隐藏的记录（无法选择隐藏，定时或受访问保护的页面中的记录！）。 参考链接： http : //wiki.typo3.org/TSref/select

您可能需要使用“ userfunc”，如下所示：

Typo脚本：

includeLibs.showHiddenElements = fileadmin/lib/showHiddenElements.php
page.20  =USER
page.20  {
 userFunc =user_showHiddenElements->main
 field = uid
 table = tt_address
 where = deleted = 0 and pid = 68
}

fileadmin / lib / showHiddenElements.php：

<?php
class user_ShowHiddenElements {
 function main($content, $conf){
    $res=  $GLOBALS['TYPO3_DB']->exec_SELECTcountRows(
                $conf[field],         // SELECT ...
                $conf[table],     // FROM ...
                $conf[where],    // WHERE...
               '',            // GROUP BY...
               '',    // ORDER BY...
               ''            // LIMIT ...
            );
    return $res;
 }
}
?>

Answer 2

您不能以正常方式绕过“启用字段” where子句，但是TYPO3允许使用UNION查询来解决：

select {
    selectFields = count(uid) AS count
    pidInList = 68
    where.data = TSFE:id
    # we hack our way around the enablefields restriction
    where.wrap = 0 UNION SELECT COUNT(*) as count FROM tt_address WHERE pid = 68
}

Answer 3

替代解决方案：

page{
24 = CONTENT
24.wrap = <div class="status_count">|</div>
24 {
    table = tt_address
    select {
        selectFields = count(uid) AS count
        pidInList = 68
        where.data = TSFE:id
        # we hack our way around the enablefields restriction
        where.wrap = |0 UNION SELECT COUNT(*) as count FROM tt_address WHERE pid = 68
    }
    renderObj = COA
    renderObj {
        10 = TEXT
        10.wrap = |</div><div style="display:none">
        10 {
            value = Status: {field:count}
            insertData = 1
        }
    }
}
}

感谢cweiske给我这个主意。

这是这样的：例如，仅显示已删除或隐藏的页面

table = pages
select.pidInList = 1
select.where = deleted=1 or hidden=1 UNION SELECT * FROM pages WHERE 1=0

这是因为将enablefields附加到查询中。 与1 = 0并集，其中子句与enablefields一起不返回任何内容。
