My thoughts

Hi, I do agree with you 1-5 point, especially 1 because i believe the focus is supposed to be on good architectures and design patterns, but your 6th point of web developers not being programmers is from a limited view. Though i don't deem myself as having arrived but at least I'm working to get better everyday, Take example of a project that I'm working on, it's web based, app that has to do with video streaming which includes a lot of things, some part has to be written in erlang and Go for concurrency issues, I have to extend a queueing system such as RabbitMQ, the app consist of various microservices built in Nodejs talking to themselves. I have to write various algorithms to test the internet capacity of the client and then stream the video resolution as required, adequately handle buffering and many more things which i can't go into detail here.

Maybe he meant to say "web-designers", cause, they aren't programmers.

BELOW IS THE SOURCE OF MY WAILING:



There is these codes that refuses to do what I think I commanded it to do. I have been on this codes for about three weeks now, doing all manner of things, including the illogical and crazy things, I even went spiritual(joking). The codes were written to insert some values gotten from the form fields into a table in the database. For some reasons unknown to me the codes didn't work as envisaged. The worst thing is no error is printed on the browser's page.

In order to debug the code, I put the where I run the SQL insert into an if-else statement(if(mysqli_query($product_insert))), but, the codes in the else block run only.

Below is the php codes:



<?php

if(isset($_POST['insert_post'])){



$product_title = $_POST['product_title'];
$product_types = $_POST['product_types'];
$product_brand = $_POST['product_brand'];
$product_size = $_POST['product_size'];
$product_price = $_POST['product_price'];
$product_desc = $_POST['product_desc'];
$product_keywords = $_POST['product_keywords'];


$product_image = $_FILES['product_image']['name'];
$product_image_tmp = $_FILES['product_image']['tmp_name'];


move_uploaded_file($product_image_tmp,'product_images/$product_image');


$insert_product = "INSERT INTO product(product_title,product_types,product_brand,product_size,product_price,product_desc,product_keywords,product_image) VALUES
('$product_title', '$product_types', '$product_brand', '$product_size', '$product_price', '$product_desc', '$product_keywords', '$product_image',)";
$insert_pro_query = mysqli_query($con, $insert_product);
if($insert_product){

echo "<script>alert('Product has been inserted')</script>";

echo "<script>window.open('insert_product.php', 'self')</script>";
}else{
echo 'not inserted';
}
}

?>



Help please larisoft, Dhtml18, Danielthegeek, SEUNTHOMAS, etc

If this is your production code, you playing with sql injection security. Big time, try escape tbe posted data with mysql_real_escape_string()

A key point of #6 is; happen to ONLY be web related CALLING upon an sql database.

Somehow, someone missed that.

Among the other things your project is about. Folks I refer to are the...Hey, here's a form, fill it, submit and query back.

Hope that's clearer now.

No it is not.

teampregar:
$insert_product = "INSERT INTO product(product_title,product_types,product_brand,product_size,product_price,product_desc,product_keywords,product_image) VALUES
('$product_title', '$product_types', '$product_brand', '$product_size', '$product_price', '$product_desc', '$product_keywords', '$product_image',)";
$insert_pro_query = mysqli_query($con, $insert_product);
if($insert_product){}

The problem is that u are using a string ($insert_product) as an expression .. U are supposed to be using the variable($insert_pro_query) which u assigned to the mysqli_query function as the expression..
it is supposed to be:
if ($insert_pro_query) {
/Codes here
}

When u do this then the codes in the if block will execute if the data was inserted into the database...

Thanks I corrected it and it is still not inserting.

DanielTheGeek:


Any variable enclosed in single quotes will be parsed as a string, don't have time to help you debug but fix this line: (there could be other errors)

move_uploaded_file($product_image_tmp,'product_images/$
product_image');

TO

move_uploaded_file($product_image_tmp,"product_images/$
product_image";

Thanks. I have done what you said but it couldn't work.

That means you have more technical errors, are you sure your tables in the database matches the one in the script?

Also data won't enter the database if the datatype being passed doesn't match the expected one for instance passing a boolean into a datetime field or if NULL is set to NO by default in this case data will not enter the db IF the field is null.

Try uploading a screenshot or share the details of the error you got when you executed the script as many many things could be wrong and may not even be from those particular lines of code you shared.

#4. Efficiency sounds like an old movie.

I have heard people who write "minimal" programs say things like; My program will run on the latest multicore CPU and have Gigabytes of RAM to play with so it should run efficiently and I can worry less.

The thing is, the more capable our computer systems get the much more things we will dream up to accomplish with them.

The thing is, even on x-core systems your program instructions don't always execute in one CPU clock cycle...some take as much as 30 cycles to finish. Add to that your CPU+L1+Lx cache and system memory reads and you now have less power than you thought.

The more you understand your choice of programming language, it's memory model, and the things your APIs do to ease development the more likely you are to create programs that can service millions of users concurrently.

The thing is, there is no error shown when I tried running the codes, the page displayed is blank. I have learnt somethings from this comment. I will check the database to see if I violated the issues you raised in your comment. Even though, eventually I did not get the solution to this problem, trust me I am learning a lot from you guys contributions. Thanks boss.

Is the page completely blank or it's showing "Not inserted" ?

If it shows "Not inserted", try to echo mysqli_error($con) to see the last error that occurred

Yes, it was blank, but, I was able to figure the problem out. It was the comma I added in the SQL, I added it after the last variable, in the parentheses after VALUES.

Thank you all for your attention.

That's how a languages can Fu** you up, just a single comma. I hit myself sometimes when I make such mistakes.

We actually have a good number of programmers in this country. I know so many. The thing is programmers tend to associate at their level. So if you have been coding for long, most likely you will find yourself in the midst of people who have been coding that long. As for if the numbers are exaggerated, i would say we have a ratio of 1/10000 very good programmers who are Nigerians. This is just a guess but i believe awareness about programming has become more rampant in the last 5 years. The future belongs to us. Don't be surprised if big companies from silicon valley start coming to shop for talents in Nigeria. Already we have a very large presence outside Nigeria but the internal workforce is growing.

Am in my early 30's. But who that one epp? But i like the fact that you took time to check his real age. Most people who have just stood at the assumption and started fight again. lol.

Especially when you check the code from beginning to end, even check it character by character and yet you couldn't still know what is wrong. That is when you start thinking spiritual things.......Don't be surprised, if you see people coding in the church, mosques and shrines ooo.

Like seriously??
I thought you are up to 50yrs (I'm not joking)
.
Since you have been programming for 18yrs then I assumed you were 18yrs or 20yrs when you started..

I started programming quite young,wish i started younger like 10 yrs old. A lesson for you to be dilligent and be appreciative of those ahead of you.

Lol wish I started more earlier... Lol I appreciate people ahead but it seems like you learnt mostly from university..

Because you're good in objective (I saw your thread about security stuff)
.
I haven't seen your code tho!

I dont have a degree in computer science but i do have a degree. And am not just good in concept or objective as you called it, i am very sound in writing code too.
In programming you learn the abstract first and then you can go into writing code, if you are not good with concepts, you will only write poor code.

I have a question shaaa

Between computer science and engineering which is better..( I'm going to school soon)

I really wanna be the next bad coder!
But people say computer science don't worth it...

What's your view?
