Question

我使用以下SQL来获取内容的位置。

$leftBlock ='l';
$rightBlock ='r';
$topBlock = 'c';
$bottomBlock = 'd';

$blockposition = array();

$result2 = $db->sql_query("SELECT bposition FROM {$prefix}_blocks_manager WHERE module_title ='$name'"); 
while($row2 = $db->sql_fetchrow($result2)) { 
$blockposition[] = $row2['bposition'];

}

$blockposition2 = array_unique($blockposition);//remove duplicates becouse db output can be like:lllrrrd
if (in_array($leftBlock, $blockposition2) AND in_array($rightBlock, $blockposition2)) {
    $mytestresult = "We go use a template with left and right blocks";
}
if (in_array($leftBlock, $blockposition2) AND !in_array($rightBlock, $blockposition2)) {
    $mytestresult = "We go use a template with just left blocks";
}
if (!in_array($leftBlock, $blockposition2) AND in_array($rightBlock, $blockposition2)) {
    $mytestresult = "We go use a template with just right blocks";
}
if (!in_array($leftBlock, $blockposition2) AND !in_array($rightBlock, $blockposition2)) {
    $mytestresult = "We go use a template with just content";
}

$name代表我正在查看的页面。

$mytestresult将告诉Twig加载特定模板：

$template = $twig->loadTemplate('mytestresult_file.phtml');

但是对于上面的每个模板，我可以创建在现有内容之上或之下添加新内容的内容。

$topBlock和$bottomBlock

在我的脚本中，我在函数blocks($side) { .....中加载所有左/右/上/下块

blocks('l') blocks('r') blocks('c') blocks('d')

如果以上4个模板中的一个还包含$topBlocks和/或$bottomBlock内容，我需要一种告诉TWIG如何渲染的方法。

默认情况下，不加载上面的4个模板中的任何一个，我就像这样渲染：

// render template
  echo $template->render(array (
              'title' => $title1,
              'metaDesc' => $metaDesc,
              'metaKeywords' => $metaKeywords,
              'navContent' => $navContent,
              'leftContent' => $leftContent,
              'defaultContent' => $module_content,
              'rightContent' => $rightContent,
              'footerContent' => $copyright
  ));

但是在这种情况下twig渲染也是右边内容的html，即使没有任何内容。

Answer 1

我通过开始创建4个默认模板解决了我的问题。

仅限默认内容
保留默认内容的内容
保留默认内容和正确内容的内容
内容正确的默认内容

我解决顶部和底部内容问题的方法是我只是添加了相关的变量默认内容，如：

$moduleContent = $topContent . $module_content . $bottomContent; //self explaining no?

我想分享我的代码作为示例，以便其他人可以使用它：

//generate template variables
$title1 = "This site is powered by smarty";
$metaDesc = "this is the coolest site on the net";
$metaKeywords = "cool,site,internet,number one,ever,created with smarty";

$module_content = $getContent['module_content']; 

$leftContent = blocks2('left');
$rightContent = blocks2('right');
$topContent = blocks2('c');
$bottomContent = blocks2('d');
$footerContent = $copyright;

//name the blockpositions (can be extended but requires hardcoding: $sliderBlock $headerBlock, $addsBlock etc etc)
$leftBlock ='l';
$rightBlock ='r';
$topBlock = 'c';
$bottomBlock = 'd';

$blockposition = array();

$result2 = $db->sql_query("SELECT bposition FROM {$prefix}_blocks_manager WHERE module_title ='$name'"); 
while($row2 = $db->sql_fetchrow($result2)) { 
$blockposition[] = $row2['bposition'];
}

//remove duplicates becouse db output can be like:lllrrrd
$blockposition = array_unique($blockposition);

////////////////////////////////////////////////////////////////
///We go check if there are top or bottom blocks are active////
//////////////////////////////////////////////////////////////

//We go add top blocks before module content and bottom blocks after module content
if (in_array($topBlock, $blockposition) AND in_array($bottomBlock, $blockposition)) {
$moduleContent = $topContent . $module_content . $bottomContent;
}
//We go add top blocks before module content
if (in_array($topBlock, $blockposition) AND !in_array($bottomBlock, $blockposition)) {
$moduleContent = $topContent . $module_content;
}
//We go add bottom blocks after module content
if (!in_array($topBlock, $blockposition) AND in_array($bottomBlock, $blockposition)) {
$moduleContent = $module_content . $bottomContent;
}

/////////////////////////////////////////////////////////////////////////////////////
/// We go check if we need left blocks and/or right blocks or no blocks at all. ////
///////////////////////////////////////////////////////////////////////////////////

//We go use a template with left and right blocks
if (in_array($leftBlock, $blockposition) AND in_array($rightBlock, $blockposition)) {
echo $twig->render('left_right.phtml', array('title' => $title1,'metaDesc' => $metaDesc,'metaKeywords' => $metaKeywords,'navContent' => $navContent,'leftContent' => $leftContent,'defaultContent' => $moduleContent,'rightContent' => $rightContent,'footerContent' => $copyright));
}
//We go use a template with just left blocks
if (in_array($leftBlock, $blockposition) AND !in_array($rightBlock, $blockposition)) {
echo $twig->render('left.phtml', array('title' => $title1,'metaDesc' => $metaDesc,'metaKeywords' => $metaKeywords,'navContent' => $navContent,'leftContent' => $leftContent,'defaultContent' => $moduleContent,'footerContent' => $copyright));
}
//We go use a template with just right blocks
if (!in_array($leftBlock, $blockposition) AND in_array($rightBlock, $blockposition)) {
echo $twig->render('right.phtml', array('title' => $title1,'metaDesc' => $metaDesc,'metaKeywords' => $metaKeywords,'navContent' => $navContent,'defaultContent' => $moduleContent,'rightContent' => $rightContent,'footerContent' => $copyright));
}
//We go use a template with just content
if (!in_array($leftBlock, $blockposition) AND !in_array($rightBlock, $blockposition)) {
echo $twig->render('content.phtml', array('title' => $title1,'metaDesc' => $metaDesc,'metaKeywords' => $metaKeywords,'navContent' => $navContent,'defaultContent' => $moduleContent,'footerContent' => $copyright));
}
