[英]How to delete " from inserted data to MySQL database
我有一個問題。
今天,我做了一個用於將數據插入MySQL數據庫的android應用程序。
當我嘗試插入String類型(例如: name )時,在記錄中顯示以下內容: “ name” 。
如何從插入的字符串中刪除“
這是我的PHP腳本:
<?php
require "connect.php";
$firstHash = substr(str_shuffle(str_repeat("0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPRSTUWYZX", 5)), 0, 5);
$secondHash = substr(str_shuffle(str_repeat("0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPRSTUWYZX", 5)), 0, 20);
$file_path_URL = "";
$id = "PRD-$firstHash-$secondHash";
$name = $_POST["name"];
$description = $_POST["description"];
$price = $_POST["price"];
$state = $_POST["state"];
$category = $_POST["category"];
$file_path = "uploads/";
$response = array();
if (isset($_FILES["upload_file"]))
{
$target_file_name = $file_path .basename("$id.png");
if(file_exists($target_file_name))
{
$success = false;
$message = "Name already exist";
}
else
{
if (move_uploaded_file($_FILES["upload_file"]["tmp_name"], $target_file_name))
{
$photoPath = "$file_path_URL$id.png";
$query = "INSERT INTO `produkty`(`ID`, `Nazwa`, `Opis`, `Cena`, `Stan`, `Zdjecie`, `Kategoria`) VALUES ('$id', '$name', '$description', $price, $state, '$photoPath', '$category')";
$result = mysqli_query($conn, $query);
if(!$result)
{
$success = false;
$message = "Error on insert data";
}
else
{
$success = true;
$message = "Add product successfuly";
}
}
else
{
$success = false;
$message = "Error while uploading";
}
}
}
else
{
$success = false;
$message = "Required Field Missing";
}
$response["success"] = $success;
$response["message"] = $message;
$json = json_encode($response);
echo ($json);
?>
負責從Android用戶獲取輸入數據的方法:
private void getValues()
{
Log.v(TAG, "getValues(): init");
EditText nameET = findViewById(R.id.nameET);
EditText descriptionET = findViewById(R.id.descriptionET);
EditText priceET = findViewById(R.id.priceET);
EditText categoryET = findViewById(R.id.categoryET);
CheckBox stateCHB = findViewById(R.id.checkBox);
String name = nameET.getText().toString();
String description = descriptionET.getText().toString();
Float price = Float.valueOf(priceET.getText().toString());
String category = categoryET.getText().toString();
boolean state;
if (stateCHB.isChecked())
{
state = true;
}
else
{
state = false;
}
sendDataToServer(name, description, price, state, category, imagePath);
Log.v(TAG, "getValues(): end");
}
我像String一樣將其發布到PHP。 這是個錯誤 ?
我是第一次從Android應用程序插入MySQL數據庫。 請幫我 !
我沒有立即看到報價的來源。 也許在“ sendDataToServer”內部,但是一種解決方案是替換
$name = $_POST["name"];
同
$name = str_replace( '"', '', $_POST["name"]);
在您的PHP代碼中,以在POST請求到達時刪除引號。
