代码不会插入数据库

Question

I have the following code that should collect the filled values from a former page and insert them in a MySQLi database. This does not work and I only get a blank page as a result, without any messages. I can't figure out what I'm doing wrong.

 <?php ini_set('display_errors',1); error_reporting(E_ALL); if(mysqli_connect_errno()) { echo mysqli_connect_error(); } $company_name = $_POST['company_name']; $description = $_POST['description']; $welcome_text = $_POST['welcome_text']; $thanks_message = $_POST['thanks_message']; $image = addslashes (file_get_contents($_FILES['image']['tmp_name'])); $logo = getimagesize($_FILES['image']['tmp_name']); $image_type = $logo['mime']; $q = "INSERT INTO project VALUES('','$company_name','$description','$image','$image_type','$welcome_text','$thanks_message')"; $r = mysqli_query($mysqli,$q); if($r) { echo "<h1>Projektet är skapat!</h1><br> Tryck på knappen nedan för att ta dig till Dashboard.<br><br> <a href='dashboardadmin.php'><button id='projectbutton'>Dashboard</button></a>"; } else { echo mysqli_errno($mysqli) . ": " . mysqli_error($mysqli) . "\\n"; } ?> 

Answer 1

Correct syntax of INSERT is:

INSERT INTO table_name (column1,column2,column3,...) VALUES (value1,value2,value3,...);

Please try entering column names before your values first. Also check your $_POST values, whether $_FILES['image'] is available and confirm your mysqli connection.

Edits:

Is the first value (empty one) your primary key? If so, can you omit that bit in your code and try again? (Assuming pid is integer and auto incrementing value.)

INSERT INTO project (project_name, description, image, image_type, welcome_text, thanks_message) VALUES('$company_name','$description','$image','$image_type','$welcome_text',‌​'$thanks_message')

Somehow I don't think this would be Azure specific issue as per your comment.

Can you see any errors in logs etc? Also try echoing the query before you run it and check if you run it directly on your phpmyadmin etc to see if it'd work.

Please also try using echo mysqli_errno($mysqli) . ": " . mysqli_error($mysqli) . "\\n"; echo mysqli_errno($mysqli) . ": " . mysqli_error($mysqli) . "\\n"; at if($r){..} else { //here } to see if you get an error.

Latest Update:

$q = "INSERT INTO project (project_name, description, image, image_type, welcome_text, thanks_message) VALUES('".$company_name."','".$description."','".$image."','".$image_type."','".$welcome_text."','".$thanks_message."')";

Answer 2

尝试此操作，因为您的主键值是自动递增的。

$q = "INSERT INTO project VALUES('$company_name','$description','$image','$image_type','$welcome_text','$thanks_message')";
