php - insert delete button of specific row from a database displayed in table -

-

hello have following code displaying database results, in 3th td of table insert delete button delete table record of data next button, should code in 3th td of tabe delete button ? 

<?php $con=mysqli_connect("localhost","table","password","database"); if (mysqli_connect_errno()) {     echo "failed connect mysql: " . mysqli_connect_error(); } $result = mysqli_query($con,"select * recetas_galletas"); echo "<table border='1'> <tr>     <th>title</th>     <th>description</th> </tr>";  while($row = mysqli_fetch_array($result)) {     echo "<tr>";     echo "<td>" . $row['title'] . "</td>";     echo "<td>" . $row['description'] . "</td>";     echo "<td>" . delete button "</td>";     echo "</tr>"; } echo "</table>"; mysqli_close($con); ?>

there several ways archive this, first , and important need field on database table can identify record want delete, example primary key in form of id or unique key.

you can creating link text delete.php page or can use jquery , ajax or can use inner form.

you want have authorized users use pages need login page session well.

you can see here example of login page sessions.

the simplest 1 link delete page, see example here:

<?php $con = mysqli_connect("localhost","table","password","database"); // check connection if (mysqli_connect_errno()) {     die("failed connect mysql: " . mysqli_connect_error()); }  if (!$result = mysqli_query($con,"select * recetas_galletas")) {     die("error: " . mysqli_error($con)); } ?> <table border='1'> <tr> <th>title</th> <th>description</th> </tr> <?php while($row = mysqli_fetch_array($result)) { ?> <tr> <td><?php echo $row['title']; ?></td> <td><?php echo $row['description']; ?></td> <td><a href="delete.php?id=<?php echo $row['id']; ?>">delete</a></td> </tr> <?php } mysqli_close($con); ?> </table>

then on delete page have this:

<?php // database info $db_host = ''; $db_user = ''; $db_pass = ''; $db_name = '';  if (!isset($_get['id'])) {     echo 'no id given...';     exit; }  $con = new mysqli($db_host, $db_user, $db_pass, $db_name); if ($con->connect_error) {     die('connect error (' . $con->connect_errno . ') ' . $con->connect_error); }  $sql = "delete recetas_galletas id = ?"; if (!$result = $con->prepare($sql)) {     die('query failed: (' . $con->errno . ') ' . $con->error); }  if (!$result->bind_param('i', $_get['id'])) {     die('binding parameters failed: (' . $result->errno . ') ' . $result->error); }  if (!$result->execute()) {     die('execute failed: (' . $result->errno . ') ' . $result->error); }  if ($result->affected_rows > 0) {     echo "the id deleted success."; } else {     echo "couldn't delete id."; } $result->close(); $con->close();

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
