我得到Parse错误:
$uphalfh = if(isset($price30in)) { echo $price30in->textContent;}
if(isset($price30out)) { echo ", " . $price30out->textContent; }
如何改进此代码以避免Parse错误? 我知道我不能在$ var
中使用IF语句当我 Echo Variable的时,它就像魅力一样,我得到了我想要的结果。但是如何将回声变量的结果(在线:10)分配给$ uphalfh
include_once './wp-config.php';
include_once './wp-load.php';
include_once './wp-includes/wp-db.php';
// A name attribute on a <td>
$price30in = $xpath->query('//td[@class=""]')->item( 1);
$price30out = $xpath->query('//td[@class=""]')->item( 2);
// Echo Variable's
if(isset($price30in)) { echo $price30in->textContent;} if(isset($price30out)) { echo ", " . $price30out->textContent; }
// The wrong CODE i tried:
// $uphalfh = if(isset($price30in)) { echo $price30in->textContent;}
// if(isset($price30out)) { echo ", " . $price30out->textContent; }
// Create post object
$my_post = array();
$my_post['post_title'] = 'MyTitle';
$my_post['post_content'] = 'MyDesciprion';
$my_post['post_status'] = 'draft';
$my_post['post_author'] = 1;
// Insert the post into the database
$post_id = wp_insert_post( $my_post );
update_post_meta($post_id,'30_min',$uphalfh);

删除作业。
if(isset($price30in)) { echo $price30in->textContent;}
if(isset($price30out)) { echo ", " . $price30out->textContent; }

// $uphalfh = you have to complete the variable initialising here and then continue with the conditional statement or remove the variable initialising and continue with the conditional statement because $var = if(conditon){ }else{ }; is wrong syntax in php
if(isset($price30in)) {
echo $price30in->textContent;
}
if(isset($price30out)) {
echo ", " . $price30out->textContent;
}

echo $uphalf = (isset($price30in)) ? $price30in->textContent : "";

if
子句不返回值,这意味着您不能在为变量赋值的上下文中使用它,因为没有值。
$uphalfh = if(isset($price30in)) {
echo $price30in->textContent;
} if(isset($price30out)) {
echo ", " . $price30out->textContent;
}
上述代码无法按预期运行,波纹管代码应按预期工作 - $uphalf
的值将设置为$price30in->textContent
或$price30out->textContent
。
if(isset($price30in)) {
$uphalfh = $price30in->textContent;
} if(isset($price30out)) {
$uphalfh = ", " . $price30out->textContent;
}
只有当您希望将此结果输出到浏览器(访问者可直接看到)时,您才能使用echo
。
if(isset($price30in)) {
$uphalfh = $price30in->textContent;
}
if(isset($price30out)) {
$uphalfh = ", " . $price30out->textContent;
}
echo $uphalfh;

一个简单的编辑就可以了!这解决了我的问题: - )
我换了:
$uphalfh = if(isset($price30in)) { echo $price30in->textContent;}
if(isset($price30out)) { echo ", " . $price30out->textContent; }
有了这个:
$uphalfh = $price30in->textContent. ', ' . $price30out->textContent;
