我遇到這個腳本的小問題。它允許用戶上傳CSV並寫入MySQL表格,同時檢查現有記錄對應表格的重複項。該腳本工作正常,除了消息報告。請看下面。在PHP腳本中報告錯誤
<?php
require_once("models/config.php"); //db connection is in this file
function get_file_extension($file_name) {
return end(explode('.',$file_name));
}
function errors($error){
if (!empty($error))
{
$i = 0;
while ($i < count($error)){
$showError.= '<div class="msg-error">'.$error[$i].'</div>';
$i ++;}
return $showError;
}// close if empty errors
} // close function
if (isset($_POST['upfile'])){
if(get_file_extension($_FILES["uploaded"]["name"])!= 'csv')
{
$error[] = 'Only CSV files accepted!';
}
if (!$error){
$tot = 0;
$handle = fopen($_FILES["uploaded"]["tmp_name"], "r");
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
for ($c=0; $c < 1; $c++) {
//only run if the first column if not equal to firstname
if($data[0] !='firstname'){
$check=mysqli_query($mysqli,"select * from persons where firstname='$data[0]' and surname='$data[1]'");
$checkrows=mysqli_num_rows($check);
if($checkrows>0){echo "$data[0] $data[1] exists in the database. Please remove this entry before uploading your records.";}
else{
$order = "INSERT INTO persons (firstname, surname, gender, email, address, city, province, postalcode, phone, secondphone, organization, inriding, ethnicity, senior, political_id) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)";
$stmt = mysqli_prepare($mysqli, $order);
mysqli_stmt_bind_param($stmt, "sssssssssssssss", $data[0], $data[1], $data[2], $data[3], $data[4], $data[5], $data[6], $data[7], $data[8], $data[9], $data[10], $data[11], $data[12], $data[13], $data[14]);
$result = mysqli_stmt_execute($stmt);
}
$tot++;}
}
}
fclose($handle);
$content.= "<div class='success' id='message'> CSV File Imported, $tot records added </div>";
}// end no error
}//close if isset upfile\\
$er = errors($error);
$content.= <<<EOF
<h3>Import CSV Data</h3>
$er
<form enctype="multipart/form-data" action="" method="post">
File:<input name="uploaded" type="file" maxlength="20" /><input type="submit" name="upfile" value="Upload File">
</form>
EOF;
echo $content;
?>
當腳本發現重複,呼應了「姓姓氏存在於數據庫中。請在上傳記錄之前刪除此條目。 CSV文件已導入,已添加1條記錄「
沒有任何內容會寫入到表格中,這是我想要的內容,但我希望信息說'已導入CSV文件,添加了0條記錄'或者根本沒有該信息當發現一個重複的,因爲這可能會混淆用戶
我知道這是一個超級簡單的解決方法(有點像放錯位置的支架),但我想不通。提前
感謝。
完美,謝謝! – JLA
