Error in sql query with php and mysql?

Error in sql query with php and mysql? - php

I got this error
You have an error in your SQL syntax; check the manual that
corresponds to your MariaDB server version for the right syntax to use
near '' at line 1
and here is my code
<?php
$titulo = "Baja de usuario";
require "conexion.php";
$usu_nombre = $_POST["usu_nombre"];
$usu_id = $_POST["usu_id"];
$sql = "DELETE FROM usuarios WHERE usu_id = ".$usu_id;
$resultado = mysqli_query($link, $sql) or die(mysqli_error($link));
$chequeo = mysqli_affected_rows($link);
include "encabezado.php";
?>
Can't really find the syntax error there, any idea?
the $_POST["usu_id"] comes from here:
$titulo = "Formulario de baja- Usuarios - Proyecto integrador";
require "conexion.php";
$usu_id = $_GET["usu_id"];
$sql = "SELECT usu_id, usu_login ,usu_clave, usu_nombre, usu_email FROM usuarios WHERE usu_id = ".$usu_id;
$resultado = mysqli_query($link, $sql) or die(mysqli_error($link));
?>
<?php include "encabezado.php"; ?>
</head>
<body>
<div id="top"><img src="imagenes/top.png" alt="encabezado" width="980" height="80"></div>
<div id="nav">
<?php include "menu.php"; ?>
</div>
<div id="main">
<h1><?php echo $titulo ; ?></h1>
<!-- inicio del desarrollo -->
<form action = "baja-usuario.php" method = "post" onsubmit = "return confirmarBaja()">
<table id="paneles">
<tr>
<th colspan ="5">Se eliminara el siguiente usuario</th>
</tr>
<tr>
<th>Id</th>
<th>Login</th>
<th>Clave</th>
<th>Nombre</th>
<th>Email</th>
</tr>
<?php while($fila = mysqli_fetch_assoc($resultado)){ ?>
<tr>
<td class = "lista"><?php echo $fila["usu_id"] ;?></td>
<td class = "lista"><?php echo $fila["usu_login"]; ?></td>
<td class = "lista"><?php echo $fila["usu_clave"] ;?></td>
<td class = "lista"><?php echo $fila["usu_nombre"] ;?></td>
<td class = "lista"><?php echo $fila["usu_email"] ;?></td>
</tr>
<?php } ?>
<tr>
<td><input type= "hidden" name = "usu_id" value = "<?php echo $fila["usu_id"]; ?>"></td>
<td><input type= "hidden" name = "usu_nombre" value = "<?php echo $fila["usu_nombre"]; ?>"></td> <!-- el input type hidden no renderiza el valor pero si sirve para pasarlo como parametro en el FROM -->
</tr>
<tr>
<td colspan = "2" class ="centrar"><input type = "submit" value = "Eliminar"></td>
</tr>
</table>
</form>
and the usu_id from the : <td class = "lista"><?php echo $fila["usu_id"] ;?></td> displays correctly, showing the ID

The error was that i was using <?php while($fila = mysqli_fetch_assoc($resultado)){ ?> and so the usu_id the form send to the POST, was empty beacuse of the msqli_fetch_assoc

File view to the another tab (PHP)

I have inserted a file with an UPDATE command because I want my files (pdf, jpg) to be in one table together with name, course, etc. and and I just want to know if it it is possible that instead of showing the name of the filename in the table, its filename would be an href on when the person have click it, it would go in the another tab to show is content (pdf, or jpeg).
Here is my code of my addrequirements.php
<?php

PROBLEM:
I just want to have a solution that instead it displays the filename of that file (text), it will show its filename in the table that is clickable to open its file in the another tab.

Yes, of course it possible. You should save also relative path to that PDF in database and then show link in UI part:
<!-- Start of table -->
<td>
Click to view
</td>
And your database table will have 1 additional field named path VARCHAR(256) NOT NULL with value e.g. students/some_name_of_file.pdf
Never store file content to database, it's not build to hold file contents

Navigate to the specific link is not working according to the database status value in php and sqlite

when i clicked the link it does not redirect to the page that specified.i have the sqlite database and there is a database column for status(added,updated like wise).i want to redirect to the page when i clicked the status link in my link.php.Now Object not found error is getting.
this is my link.php code below.
Please can you help me guys.
<?php
// Includs database connection
include "db_connect.php";
// Makes query with rowid
$query = "SELECT rowid, * FROM registration";
// Run the query and set query result in $result

How to delete row of table with a button inside

I have a table generated with The foreach construct, on each <tr> there is a delete button inside. I want to delete the row containing the button (by the ID) but all I've done is delete the last row (the last ID) that was saved and not the desired.
This is a part of my HTML code:
<form action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?>" method="POST">
<table class="Pizarra" id="pizarra" cellspacing="0px";>
<tr class="trThDos">
<th></th>
<th></th>
<th></th>
<th></th>
<th></th>
</tr>
<tbody>
<!-- Comienza PHP -->
<?php
$i = 0;
foreach ($resultados as $fila)
{
?>
<tr>
<input type="hidden" name="id" value="<?php echo $fila['ID']; ?>" />
<td class="tdTurno"><?php echo '#' . ++$i ?></td>
<td class="tdImg">
<?php echo $fila ['value'];
switch ($fila['value'])
{
case "0":
echo "<img src='./img/consulta-56-2.png'";
break;
case "1":
echo "<img src='./img/shot-56-2.png'";
break;
case "2":
echo "<img src='./img/ta-56-2.png'";
break;
case "3":
echo "<img src='./img/cert-56-2.png'";
break;
default:
echo "Hubo un error en la selección";
break;
} ?>
</td>
<td>
<?php echo $fila ['nombre']; ?>
</td>
<td class="tdHr">
<?php echo $fila ['hora']; ?>
</td>
<td>
<input type="submit" class="btnBorrar" name="btnBorrar" value="X">
</td>
</tr>
<?php } ?>
</tbody>
</table>
</form>
PHP code:
<?php
// ----------- CONEXIÓN ------------------
try {
$conexion = new PDO('mysql:host=localhost;dbname=farmacia', 'Emm', ' ');
$conexion->exec("set names utf8");
//echo "Conexión OK <br />";
}catch(PDOException $e){
echo "Error: " . $e->getMessage();
die();
}
// ----------- TERMINA CONEXIÓN -----------------
if(isset($_POST['btnBorrar'])){
$id = $_POST['id'];
$statement = $conexion->prepare("DELETE FROM eventos WHERE ID = $id");
$statement->execute();
//fetchAll' es clave para que invoque (llame) TODOS los elementos
$resultados = $statement->fetchAll();
header("Location:index.php");
$conexion = null;
}
?>

Use GET method instead of POST
In your HTML instead of using submit button use link as shown in below
X
In the delete.php do like following
<?php
if(isset($_GET['id'])){
//get the id into php variable like below
$id = $_GET['id'];
//sql query to delete with id variable in where clause
}
?>
Hope this work!!!

Try with below code..
HTML
<form action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?>" method="POST">
<table class="Pizarra" id="pizarra" cellspacing="0px";>
<tr class="trThDos">
<th></th>
<th></th>

<td><input type="button" class="btnBorrar" name="btnBorrar" value="X" onClick="delete_row(<?php echo $fila['ID']; ?>)"></td>
</tr>
<?php } ?>
</tbody>
</table>
</form>
JavaScript
function delete_row(delete_id) {
$.ajax({
type: "POST",
url: 'delete_row.php',
data: 'delete_id='+delete_id,
success: function(data_respones){
$("#row_id_"+delete_id).remove();
}
});
}
delete_row.php
<?php
// ----------- CONEXIÓN ------------------
try {
$conexion = new PDO('mysql:host=localhost;dbname=farmacia', 'Emm', ' ');
$conexion->exec("set names utf8");
//echo "Conexión OK <br />";
}
catch(PDOException $e){
echo "Error: " . $e->getMessage();
die();
}
if(isset($_POST["delete_id"])){
//do delete stuff
$statement = $conexion->prepare("DELETE FROM eventos WHERE ID = $id");
$statement->execute();
}
?>

Instead of using POST method, use GET and give your delete button a link like
yourscript.php?delete={ID}
and handle your id like
$deleteId = (int)$_GET["delete"];
and
if(isset($deleteId)){
//do delete stuff
$statement = $conexion->prepare("DELETE FROM eventos WHERE ID = $deleteId");
$statement->execute();
//fetchAll' es clave para que invoque (llame) TODOS los elementos
$resultados = $statement->fetchAll();
}
Replace your hidden input field with this;
<a href="yourscript.php?delete=<?php echo $fila['ID']; ?>">Delete me</>

trouble in using $_SESSION in PHP
