我没有构建这个PHP文件,但我想弄清楚它为什么会给我错误。如果" Block布局模式" ACF变量设置为"模态"然后块工作,但给了我这个错误。 "第176行和第34行的未定义变量$ vids。如果我选择"嵌入&缩图"模式,然后没有显示块,我收到此错误。 "在第252行和第34行调用未定义的函数vc_embed_layout();我无法确定为什么会发生这种情况,而且我还没能在我的php文件中找到任何未关闭的标签或任何内容。这是有问题的文件,我已经标记了触发错误的行。

答案 0 :(得分:1)
您不接受vc_modal_layout()
函数声明中的任何参数。
if (!function_exists('vc_embed_layout')) {
function vc_embed_layout() {
需要有参数才能接受参数。
这样的事情是你正在寻找的:
if (!function_exists('vc_embed_layout')) {
function vc_embed_layout($vids=[], $i=0) {
与vc_modal_layout
的想法相同,该函数需要能够从外部接受变量。
当我们调用一个函数时,该函数需要能够接受传递给它的所有参数。我们使用的所有变量都需要定义,如果存在未定义或空数组的风险,我们可以使用if(!empty($var))
或if(isset($var))
将变量传递给函数的另一种方法是将其作为全局访问。但是将变量传递给函数通常会更好,因为当我们将变量传递给PHP中的函数时,它会使用函数内部变量值的副本。当我们做这样的事情时:
$var = 10;
function doIt(){
global $var;
$var++;
}
doit();
echo $var;
我们可能会使事情过于复杂..
让我们仔细看看:
if ($layout == 'modal') vc_modal_layout($vids);
if ($layout == 'embed') vc_embed_layout($vids, $i); ?> **This is line 252**
function vc_modal_layout(){ ... }
// should be:
function vc_modal_layout($vids){ ... }
function vc_embed_layout($vids, $i)
// looks good.
除此之外,没有什么能像真正不同寻常的那样突出。我想看一下实际的网站,以便进一步修补这个问题。
