I think the problem might be that you need square brackets instead of parenthesis since it's an array. <code>$request['idprestamo']</code>
<code>$request['numeropago']</code>
<code>$request['payqty']</code>

I'd like to also add that you can do it this way also with a magic method...

<code>$request-&gt;numeropago</code>

You have to access the <code>Request</code> this way <code>$request-&gt;input_name</code> not this way <code>$request('input_name')</code> because it is a <a href="https://laravel.com/docs/5.7/collections" rel="nofollow noreferrer">Laravel Data Collection</a>

In the end of the day, your function will look like this:

<pre><code>public function update(Request $request)
 {
 $idpawn = $request-&gt;idprestamo;
 $paynumber = $request-&gt;numeropago;
 $payqty = $request-&gt;payqty;
 $statuspawns = statuspawns::find($idpawn,$paynumber);
 $updateqty = $statuspawns-&gt;totalpayment - $payqty;

 if($updateqty == "0"){
 $status = "Pay";
 }
 else{
 $status = "Partial Payment";
 }

 $statuspawns-&gt;total = $updateqty;
 $statuspawns-&gt;status = $status;
 $statuspawns-&gt;save();

 return redirect()-&gt;back();
 }
</code></pre>

<h1>UPDATE</h1>

In Laravel 5.7 you have to use the <code>update()</code> method instead of the <code>save()</code> method to update a row.

blocks|key|1281102|text|您没有正确检索记录。您必须只将id传递给find()。因为你已经传递了两个参数。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|1281103|将此语句更改为.。|1281104|$statuspawns+=+statuspawns::find($idpawn,$paynumber);|code-block|syntax|javascript|1281105|至|1281106|$statuspawns+=+statuspawns::find($idpawn);|1281107|现在，您可以更新要更新的列。|1281108|entityMap^0|K|6|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|X|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|Y|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|Z|8|@]|D|@]|E|$]]|$1|O|3|P|5|J|7|10|8|@]|D|@]|E|$K|L]]|$1|Q|3|R|5|6|7|11|8|@]|D|@]|E|$]]|$1|S|3|-4|5|6|7|12|8|@]|D|@]|E|$]]]|T|$]]

You are not retrieving the record correctly. you have to pass only id to find(). As you have passed two parameters.

change this statement to..

<pre><code>$statuspawns = statuspawns::find($idpawn,$paynumber);
</code></pre>

To

<pre><code>$statuspawns = statuspawns::find($idpawn);
</code></pre>

Now you can update the columns which you want to update.

I'm trying to update a row in mysql table. However, when I click the register button, it doesn't do anything. I'm using Laravel.

Here's my <code>update</code> function:

<pre><code>public function update(Request $request)
{
 $idpawn = $request['idprestamo'];
 $paynumber = $request['numeropago'];
 $payqty = $request['payqty'];
 $statuspawns = statuspawns::find($idpawn,$paynumber);
 $updateqty = $statuspawns-&gt;totalpayment - $payqty;

 if($updateqty == "0"){
 $status = "Pay";
 }
 else{
 $status = "Partial Payment";
 }

 $statuspawns-&gt;total = $updateqty;
 $statuspawns-&gt;status = $status;
 $statuspawns-&gt;save();

 return redirect()-&gt;back();
}
</code></pre>

Thanks for your help.
