如果我运行此代码，就会得到所需的结果
<?php
$terms = get_terms( \'call-type\' );
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
foreach ( $terms as $term ) {
echo \'\\\'\' . $term->name . \'\\\', \';
}
}
?>
result
\'“全部”、“已完成”、“正在进行”、“新建”，
但是，如果我将相同的代码放入选项的所有选择框中，则会在结果中添加斜杠。
<select class="w-100" name="mf_term">
<option value="
<?php
$terms = get_terms( \'call-type\' );
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
foreach ( $terms as $term ) {
echo \'\\\'\' . $term->name . \'\\\', \';
}
}
?>
">All</option>
result
\\\'“全部”、“已完成”、“进行中”、“新建”，
How can I remove the slashes from the option in the select box

SO网友:WP Updoot
你需要做的是双倍逃跑，所以改变echo \'\\\'\' . $term->name . \'\\\', \'; 到echo \'\\\\\\\'\' . $term->name . \'\\\\\\\', \';
。。。但是，您最好只使用不同的封装器：
<select class="w-100" name="mf_term">
<option value="
<?php
$terms = get_terms( \'call-type\' );
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
foreach ( $terms as $term ) {
echo "\'{$term->name}\', ";
}
}
?>
">All</option>
当您回显一个字符串，而不是直接将内容附加到HTML中时，您可以使用双引号来封装输出，而无需担心过早意外退出select对象。
此外，在对标准PHP变量使用双引号时($myVariable) 或类/对象属性($myClass->myProperty / $myObject->myProperty) 您只需将其插入，PHP就会正确地评估它（我喜欢添加大括号以便更好地衡量，但这不是绝对必需的）；这意味着你根本不需要逃逸字符串。
最后您提交的代码只会在下拉列表中创建一个选项，值为\'All\', \'Completed\', \'In progress\', \'New\',. 如果您希望在选择框中列出选项列表（以便您可以选择All, Completed, In progress or New), 以下可能更有效：
<select class="w-100" name="mf_term">
<?php
$terms = get_terms( \'call-type\' );
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
foreach ( $terms as $term ) {
echo "<option value=\'{$term->name}\'>{$term->name}</option>";
}
}
?>
</select>
