PDO無法將廣告類型的對象用作數組（格式錯誤）
[英]PDO Cannot use object of type ads as array (form error)
問題描述
我是PDO的新手，正在嘗試制作廣告網站。 在包含來自表單的數據的頁面上，我收到以下問題：“致命錯誤。無法將ads類型的對象用作數組”。 在這里問之前，我搜索了這個問題，但沒有找到任何東西（也許是因為我是新手？）。 請不要對我投反對票。
這是具有以下功能的PHP文件：
class ads{
private $db;
public function __construct($database) {
$this->db = $database;
}
public function insert_ads($categorie, $subcategorie, $userid, $site, $nume, $oras, $judet, $telefon, $email, $titlu_anunt, $text_anunt, $pret_anunt ){
$time = time();
$categorie = 'masini';
$subcategorie = 'dacia';
$email_code = $email_code = uniqid('code_',true);
$query = $this->db->prepare("INSERT INTO `ads` (`categorie`, `subcategorie`, `userid`, `site`, `nume`, `oras`, `judet`, `telefon`, `email`, `email_code`, `titlu_anunt`, `text_anunt`, `pret_anunt`, `data_adaugare`, `vizualizari`, `confirmed`, `platit`) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) ");
$query->bindValue(1, $categorie);
$query->bindValue(2, $subcategorie);
$query->bindValue(3, 0);
$query->bindValue(4, $site);
$query->bindValue(5, $nume);
$query->bindValue(6, $oras);
$query->bindValue(7, $judet);
$query->bindValue(8, $telefon);
$query->bindValue(9, $email);
$query->bindValue(10, $email_code);
$query->bindValue(11, $titlu_anunt);
$query->bindValue(12, $text_anunt);
$query->bindValue(13, $pret_anunt);
$query->bindValue(14, $time);
$query->bindValue(15, 1);
$query->bindValue(16, 0);
$query->bindValue(17, 0);
try{
$id_last = ("SELECT LAST_INSERT_ID()");
$result = $this->db->prepare($id_last);
$result->execute();
$last_id = $result->fetchColumn();
#code to deal with the picture uploads
#target folder
$target = 'image_uploads/';
if(isset($_FILES['image_name'])===true){
$files = $_FILES['image_name'];
for($x = 0 ; $x < count($files['name']); $x++){
$name = $files['name'][$x] ;
$temp_name = $files['tmp_name'][$x];
#extention filter it takes only the extension want
$allowed ='gif,png,jpg';
$extension_allowed= explode(',',$allowed );
$file_extention = pathinfo($name, PATHINFO_EXTENSION);
if(array_search($file_extention,$extension_allowed)){
}else {
echo 'We only allow gif, png ,jpg';
exit();
} #extention filter ends here
#check the size of the image
$file_size = $files['size'][$x];
if($file_size > 2097152){
echo 'The file should be lesS than 2MB';
exit();
}
#check the size of the image ends here
#Rename images
$sub = substr(md5(rand()),0,7);
#the above generates char and numbesr
$rand = rand(0,100000);
$rename = $rand.$sub.$name;
#Rename images ends here
$move = move_uploaded_file($temp_name,$target.$rename);
#code to deal with the picture uploads ends here
$images ="INSERT INTO ads_images(ads_id,image_name)
VALUES($last_id,:image_name)";
$images_insert = $this->db->prepare($images);
$images_insert->execute(array(
':image_name'=>$rename,
));
}}
$query->execute();
mail($email, 'Please activate your account', "Hello " . $nume. ",\r\nThank you for registering with us. Please visit the link below so we can activate your account:\r\n\r\nhttp://www.djmixtv.com/test/activate_ads.php?email=" . $email . "&email_code=" . $email_code . "\r\n\r\n-- Example team");
}catch(PDOException $e){
die($e->getMessage());
}
}
這是PHP代碼：
if (isset($_GET['success']) && empty($_GET['success'])) {
echo '<h3>Your details have been updated!</h3>';
} else{
if(empty($_POST) === false) {
if (isset($_POST['nume']) && !empty ($_POST['nume'])){ // We only allow names with alphabets
if (ctype_alpha($_POST['nume']) === false) {
$errors[] = 'Please enter your Name only with letters!';
}
}
if (isset($_POST['oras']) && !empty ($_POST['oras'])){
if (ctype_alpha($_POST['oras']) === false) {
$errors[] = 'Please enter your city with only letters!';
}
}
if (isset($_POST['judet']) && !empty ($_POST['judet'])){
if (ctype_alpha($_POST['judet']) === false) {
$errors[] = 'Please enter your contry with only letters!';
}
}
if (isset($_POST['telefon']) && !empty ($_POST['telefon'])){
if (ctype_digit($_POST['telefon']) === false) {
$errors[] = 'Please enter your phone with only numbers!';
}
}
if (isset($_POST['telefon']) && !empty ($_POST['telefon'])){
if (ctype_digit($_POST['telefon']) === false) {
$errors[] = 'Please enter your phone with only numbers!';
}
}
if (filter_var($_POST['email'], FILTER_VALIDATE_EMAIL) === false) {
$errors[] = 'Please enter a valid email address';
}
if (isset($_POST['titlu_anunt']) && !empty ($_POST['titlu_anunt'])){
if (ctype_alnum($_POST['titlu_anunt']) === false) {
$errors[] = 'Please enter your phone with only numbers!';
}
}
$site = htmlentities(trim($_POST['site']));
$nume = htmlentities(trim($_POST['nume']));
$oras = htmlentities(trim($_POST['oras']));
$judet = htmlentities(trim($_POST['judet']));
$telefon = htmlentities(trim($_POST['telefon']));
$email = htmlentities(trim($_POST['email']));
$titlu_anunt = htmlentities(trim($_POST['titlu_anunt']));
$text_anunt = htmlentities(trim($_POST['text_anunt']));
$pret_anunt = htmlentities(trim($_POST['pret_anunt']));
$ads->insert_ads($categorie, $subcategorie, $site, $nume, $oras, $judet, $telefon, $email, $titlu_anunt, $text_anunt, $pret_anunt);
header('Location: settings.php?success');
exit();
}
形式如下：
<form action="" method="post" enctype="multipart/form-data">
<div id="personal_info">
<h3 >Change Profile Information </h3>

<li>

<input type="text" name="site" value="<?php if (isset($_POST['site']) ){echo htmlentities(strip_tags($_POST['site']));} else { echo $ads['site']; }?>">

這與PDO不相關。
您不能將ads實例用作數組。 例如
$ads = new ads();
$ads['something'] = 1; //Fatal Error comes here
它隨處可見。
<input type="text" name="site" value="<?php if (isset($_POST['site']) ){
echo htmlentities(strip_tags($_POST['site']));} else { echo $ads['site']; }
?>">
在PHP中，如果要使用屬性，則必須對其進行定義。
class ads {
public myProperty;
public function setAValueForMyProperty(){
$this->myProperty = 1;
}
}
$ads = new ads();
$ads->setAValueForMyProperty();
echo $ads->myProperty;
如果要將類實例用作數組，則有兩個選擇。 您可以將其內容導出到數組中：
class ads {
protected myProperty = 1;
public function toArray(){
return array(
'myProperty' => $this->myProperty;
);
}
}
$ads = new ads();
$arr = $ads->toArray();
echo $arr['myProperty'];
或者，您可以實現ArrayAccess接口：
class ads implements ArrayAccess {
protected myProperty = 1;
public function offsetSet($offset, $value) {
$this->$offset = $value;
}
public function offsetExists($offset) {
return isset($this->$offset);
}
public function offsetUnset($offset) {
unset($this->$offset);
}
public function offsetGet($offset) {
return $this->$offset;
}
}
$ads = new ads();
echo $ads['myProperty'];
我認為您應該閱讀更多有關php中類如何工作的信息。
