我有這個php文件,它將更新mysql數據庫中的表。更新MySQL數據庫和id和圖像相關的ID?
它工作到一定程度。它會更新產品的名稱(product_name),它也會更新(date_added)。但它並沒有更新ID,因此使用該ID上傳的圖像沒有顯示!
這裏是代碼:
<?php
// Parse the form data and add inventory item to the system
if (isset($_POST['product_name'])) {
$product_name = mysql_real_escape_string($_POST['product_name']);
// See if that product name is an identical match to another product in the system
$sql = mysql_query("SELECT id FROM tomProduct WHERE product_name='$product_name' LIMIT 1");
$productMatch = mysql_num_rows($sql); // count the output amount
if ($productMatch > 0) {
echo 'Sorry you tried to place a duplicate "Product Name" into the system, <a href="index.php">click here</a>';
exit();
}
// Add this product into the database now
$sql = mysql_query("UPDATE tomProduct SET product_name='$product_name', date_added=now()") or die (mysql_error());
$pid = mysql_insert_id();
// Place image in the folder
$newname = "$pid.jpg";
move_uploaded_file($_FILES['fileField']['tmp_name'], "../tom/$newname");
header("location: verify_members.php");
exit();
}
?>
,這裏是形式:
<form action="verify_members.php" enctype="multipart/form-data" name="myForm" id="myform" method="post">
<table width="90%" border="0" cellspacing="0" cellpadding="6">
<tr>
<td width="20%" align="right">Product Name</td>
<td width="80%"><label>
<input name="product_name" type="text" id="product_name" size="64" />
</label></td>
</tr>
<tr>
<td align="right">Product Image</td>
<td><label>
<input type="file" name="fileField" id="fileField" />
</label></td>
</tr>
<tr>
<tr>
<td> </td>
<td><label>
<input type="submit" name="button" id="button" value="Add This Item Now" />
</label></td>
</tr>
</table>
</form>
人知道爲什麼會這樣?
感謝
爲什麼你使用'UPDATE'來'INSERT'記錄到數據庫中?該更新查詢將分別將所有product_name和date_added字段設置爲「$ product_name」和「now()」。 – Crontab 2013-03-27 13:30:50
我沒有在任何地方看到實際的INSERT。 – isotrope 2013-03-27 13:31:26
**不要在新代碼中使用'mysql_ *'函數**([why?](http://stackoverflow.com/questions/12859942/why-shouldnt-i-use-mysql-functions-in-php )),它們是 [已棄用](https://wiki.php.net/rfc/mysql_deprecation)。使用[PDO或MySQLi](http://php.net/manual/en/mysqlinfo.api.choosing.php)代替 – kero 2013-03-27 13:32:23
