Question

<?php
if(get_field('member_only_content')){
    echo "do something";
}else{
    echo "do something else";
}
?>

如何在显示"do something"的位置插入HTML代码？删除echo "do something";并粘贴HTML代码时，Wordpress网站崩溃。

Answer 1

关闭并打开PHP块，如下所示：

if(get_field('member_only_content')){
?>
    <html></html>
<?php
} else{
?>
    <html></html>
<?php
}

您也可以使用PHP的替代语法：

if(get_field('member_only_content')): ?>
    <html></html>
<?php else: ?>
    <html></html>
<?php endif;

Answer 2

喜欢这个！

<?php
if(get_field('member_only_content')) : ?>
    <div>Html stuff</div>
<?php else : ?>
    <div>More Html stuff</div>
<?php endif;

Answer 3

用HTML代替字符串。

<?php
if(get_field('member_only_content')){
    echo "<your>HTML here</your>";
}else{
    echo "<other>HTML</other>";
}
?>

你也可以打破PHP标签

<?php
if(get_field('member_only_content')){
    ?> 
    <your>HTML here</your>
    <?
}else{

    ?>
     <other>HTML</other>
    <?
}
     ?>

Answer 4

或者您可以使用＆lt;＆lt;＆lt;语句：

echo <<<END
This uses the "here document" syntax to output
multiple lines with $variable interpolation. Note
that the here document terminator must appear on a
line with just a semicolon. no extra whitespace!
END;

Answer 5

示例代码

echo("<h1>This is a sample</h1>");

Answer 6

那是因为你将HTML代码放在php标签（<?php ?>）中。此标记内的文本被解释为PHP指令，因此它不会呈现HTML。在PHP文件中有两种通用方式呈现HTML：

回应HTML

<?php

    if (get_field ('member_only_content')) {
        echo "<span>Put HTML here</span>";
    }
    else {
        echo "<span>Put HTML here</span>";
    }
?>

将HTML放在PHP标签

之外

<?php if (get_field ('member_only_content')): ?>
    <span>Put HTML here</span>
<?php else: ?>
    <span>Put HTML here</span>
<?php endif;?>

Answer 7

<?php
if(get_field('member_only_content')){
    echo "<div style='background-color: #888888'>This is a simple string between div's, make sure you've to be careful while inserting too many single and double quotes in this string as well as inline styles</div>";
}else{
    echo "do something else";
}
?>

在字符串中插入引号时要小心。
