PHP-Post语法错误

这是我从中得到语法错误的代码

<?php 
    if ($_POST['prestiti']){
        echo "<option value=".$_POST['prestiti']." 
        selected='selected'>.$_POST['prestiti']</option>";}    
    else{
        echo "<option value='No' selected='selected'>No</option>";}
?>

提前谢谢你

您有连接错误。您的错误在以下行：

selected='selected'>。$\u POST['prestiti']

您忘记了一个

“

我已经在下面的代码中修复了这些错误

<?php 
     if ($_POST['prestiti']){
        echo "<option value=".$_POST['prestiti']." selected='selected'>".$_POST['prestiti']."</option>";}
     else{
        echo "<option value='No' selected='selected'>No</option>";
    }
?>

像这样尝试

if (isset($_POST['prestiti']) && $_POST['prestiti'] != ""){
   echo "<option value=".$_POST['prestiti']." selected='selected'>" . $_POST['prestiti'] ."</option>";
}else{
   echo "<option value='No' selected='selected'>No</option>";
}

if（isset（$\u POST['prestiti']）和&&$\u POST['prestiti']！=“”）{
回显“$_POST['prestiti']”；
}否则{
回应“否”；
}

if (isset($_POST['prestiti']) && $_POST['prestiti'] != ""){
   echo "<option value=".$_POST['prestiti']." selected='selected'>" . $_POST['prestiti'] ."</option>";
}else{
   echo "<option value='No' selected='selected'>No</option>";
}
