Question

我有一个看起来像语法问题，但我得到零错误。首先，我测试了每个变量，以确保它们被表单正确填充，因此没有问题。当“$ RespondentOrPetitioner”标记为“r”或“p”时，它应该使用以下内容将数据添加到我的MySQL数据库中：

if ($RespondentOrPetitioner == "p") {
    $sql = "REPLACE INTO alkouric_darling.customer(CaseNumber, PetitionerFirstName, PetitionerLastName, RespondentFirstName, RespondentLastName, RespondentAttorneyFullName, PetitionerAttorneyFullName )
      VALUES ('$CaseNumber','$PetitionerFirstName', '$PetitionerLastName', '$RespondentFirstName', '$RespondentLastName','$RespondentAttorneyFullName','$AttorneyFullName')";
    mysqli_query($conn, $sql) or die(mysqli_error($conn));
}

但是，这并不是为这些字段更新数据库“RespondentFirstName，RespondentLastName，PetitionerFirstName，PetitionerLastName，PetitionerAttorneyFullName”和“RespondentAttorneyFullName。”

我尝试将小的$ sql语句复制/粘贴到一个单独的文件中，它工作正常，所以为什么它不适用于我的文档？每个其他MYSQL代码都适用于本文档，但“IF”语句中的2个代码不适用。我花了好几个小时试图解决这个问题并通过多个PHP语法检查程序运行它，我仍然无法弄明白，任何帮助都将不胜感激。

以下是整个代码：

<?php
$servername = "99.99.99.99";
$username = "darling";
$password = "****";
$dbname = "alkouric_darling";
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// enter San Bernardino court info
if ($CourtCounty == "San Bernardino") {
    $sql = "REPLACE INTO alkouric_darling.customer(CaseNumber, CourtCounty, CourtStreetAddress, CourtMailingAddress, CourtCity, CourtZip, CourtBranchName)
          VALUES ('$CaseNumber', 'San Bernardino', '351 N. Arrowhead Ave', '351 N. Arrowhead Ave', 'San Bernardino', '92415-0245', 'Family Law')";
    mysqli_query($conn, $sql) or die(mysqli_error($conn));
}

// enter Los Angeles court info
if ($CourtCounty == "Los Angeles") {
    $sql = "REPLACE INTO alkouric_darling.customer(CaseNumber, CourtCounty, CourtStreetAddress, CourtMailingAddress, CourtCity, CourtZip, CourtBranchName)
          VALUES ('$CaseNumber','Los Angeles', '351 N. Arrowhead Ave', '351 N. Arrowhead Ave', 'San Bernardino', '92415-0245', 'Family Law')";
    mysqli_query($conn, $sql) or die(mysqli_error($conn)); 
}

// enter Orange court info
if ($CourtCounty == "Orange") {
    $sql = "REPLACE INTO alkouric_darling.customer(CaseNumber, CourtCounty, CourtStreetAddress, CourtMailingAddress, CourtCity, CourtZip, CourtBranchName)
          VALUES ('$CaseNumber','Orange', '341 The City Drive', '341 The City Drive ', 'Orange', '92868-3209 ', 'Family Law')";
    mysqli_query($conn, $sql) or die(mysqli_error($conn));
}

// enter Respondent / Petitioner Information
if ($RespondentOrPetitioner == "p") {
    echo "<b>Respondent/Petitioner Info</b><br>";
    echo "Petitioner (you):  ".$PetitionerFirstName." ".$PetitionerLastName;
    echo "<br>Attorney(yours): ".$AttorneyFullName;
    echo "<br>Respondent: ".$RespondentFirstName." ".$RespondentLastName;
    echo "<br>Attorney (theirs): ".$RespondentAttorneyFullName;
    $sql = "REPLACE INTO alkouric_darling.customer(CaseNumber, PetitionerFirstName, PetitionerLastName, RespondentFirstName, RespondentLastName, RespondentAttorneyFullName, PetitionerAttorneyFullName )
          VALUES ('$CaseNumber','$PetitionerFirstName', '$PetitionerLastName', '$RespondentFirstName', '$RespondentLastName','$RespondentAttorneyFullName','$AttorneyFullName')";
    mysqli_query($conn, $sql) or die(mysqli_error($conn));
}

// enter Respondent / Petitioner Information
if ($RespondentOrPetitioner == "r") {
    echo "<b>Respondent/Petitioner Info</b><br>";
    echo "Petitioner:  ".$PetitionerFirstName." ".$PetitionerLastName;
    echo "<br>Attorney (theirs): ".$PetitionerAttorneyFullName;
    echo "<br>Respondent(you): ".$RespondentFirstName." ".$RespondentLastName;
    echo "<br>Attorney(yours): ".$AttorneyFullName;
    $sql = "REPLACE INTO alkouric_darling.customer(CaseNumber, RespondentFirstName, RespondentLastName, PetitionerFirstName, PetitionerLastName, RespondentAttorneyFullName, PetitionerAttorneyFullName )
          VALUES ('$CaseNumber','$RespondentFirstName', '$RespondentLastName', '$PetitionerFirstName', '$PetitionerLastName','$AttorneyFullName', '$PetitionerAttorneyFullName')";
    mysqli_query($conn, $sql) or die(mysqli_error($conn));
}

mysqli_close($conn);
