在vtiger中，数据库中有一个名为vtiger_field的表，存储与字段相关的所有内容。该表有一个名为sequence的列，表示这些字段的位置。虽然可以使用php代码修改字段的位置，但我想知道是否有一种方法可以使用Vtlib移动字段位置。
这个问题也适用于修改表Vtiger_blocks中的块的位置

$blockData =  array();
        // Get tabid
        $sql = mysql_query("SELECT tabid FROM vtigercrm71.vtiger_tab where name = 'ServiceContracts';",$DBconn); 
        $row = mysql_fetch_assoc($sql);
        $moduleId = $row['tabid'];        

        // get BlockId of the block intended to be moved
        $sql = mysql_query("SELECT blockid FROM vtigercrm71.vtiger_blocks where blocklabel = 'Renewal Details';",$DBconn); 
        $row = mysql_fetch_assoc($sql);
        $blockId = $row['blockid'];     

        // get sequence of the block to be moved under
        $sql = mysql_query("SELECT sequence FROM vtigercrm71.vtiger_blocks where blocklabel = 'LBL_SERVICE_CONTRACT_INFORMATION';",$DBconn); 
        $row = mysql_fetch_assoc($sql);
        $blockSequence = $row['sequence']; 

        // Get blocks in that module
        $sql = mysql_query("SELECT blockid,sequence FROM vtigercrm71.vtiger_blocks where tabid = ".$moduleId.";",$DBconn); 
        while($row = mysql_fetch_assoc($sql))
        {
            $blockData[] = array(
                'blockid' => $row['blockid'],
                'sequence' => $row['sequence']
            ); 
        }

        $moveToSequence = $blockSequence + 1; //No of sequence need to be moved to
        $targetSequence = null;

        // set the sequence of the block needed to be moved
        foreach($blockData as $block)
        {
            if ($blockId == $block['blockid'])
            {
                $targetSequence = $block['sequence'];
                break;
            }
        }

        // Update the block sequences from a lower sequence to a higher sequence
        foreach($blockData as $block)
        {
            $sequence = $block['sequence'];
            $blockId = $block['blockid'];
            if($block['sequence'] == $targetSequence)
            {
                $sequence = $moveToSequence;
            }
            elseif ($block['sequence'] >= $moveToSequence && $block['sequence'] < $targetSequence)
            {
                $sequence = $block['sequence'];
                $sequence + 1;
            }
            mysql_query("UPDATE vtigercrm71.vtiger_blocks SET sequence = '".$sequence."' WHERE (blockid = '".$blockId."');",$DBconn);
        }

以上是我自己编写的代码来改变一个块的顺序/位置。所有这些对于移动一个块的顺序来说都太长太乱了，这就是为什么我试图找到一种方法来改变顺序，而不是使用vtlib。

**2023年4月12日编辑：**在尝试找到当我使用CRM编辑块位置时出现的弹出窗口后，我想我设法找到了用于修改块的代码。然而，我不能完全理解它是如何工作的，加上有2个文件具有相同的功能，但不同的存储库。

在'VtigerCRM/layouts/vlayout/modules/Settings/LayoutEditor/resources/LayoutEditor.js'中的一个：

            'items' : table,

            'tolerance':'pointer',
            'cursor' : 'move',
            'update' : function(e, ui) {

            'blockInfo' : {
                'enabled' : true
            }

        var sequence = JSON.stringify(thisInstance.updateBlocksListByOrder());

现在如果我按照Ruben的建议，我将不知道如何使用这些函数来修改块
