PHP & MySQL - Deleting table rows problem.
- by oReiLLy
Okay my script is supposed to delete a specific users case which is stored in 2 MySQL tables but for some reason when the user deletes the specific case it deletes all the users cases I only want it to delete the case the user selects. I was wondering how can I fix this problem? Thanks in advance for helping.
Here is the PHP & MySQL code.
if(isset($_POST['delete_case'])) {
$cases_ids = array();
$mysqli = mysqli_connect("localhost", "root", "", "sitename");
$dbc = mysqli_query($mysqli,"SELECT cases.*, users_cases.* FROM cases INNER JOIN users_cases ON users_cases.cases_id = cases.id WHERE users_cases.user_id='$user_id'");
if (!$dbc) {
print mysqli_error($mysqli);
} else {
while($row = mysqli_fetch_array($dbc)){
$cases_ids[] = $row["cases_id"];
}
}
foreach($_POST['delete_id'] as $di) {
if(in_array($di, $cases_ids)) {
$mysqli = mysqli_connect("localhost", "root", "", "sitename");
$dbc = mysqli_query($mysqli,"DELETE FROM users_cases WHERE cases_id = '$di'");
$dbc2 = mysqli_query($mysqli,"DELETE FROM cases WHERE id = '$di'");
}
}
}
Here is the XHTML code.
<li>
<input type="text" name="file[]" size="25" />
<input type="text" name="case[]" size="25" />
<input type="text" name="name[]" size="25" />
<input type="submit" name="delete_case" id="delete_case" value="Delete Case" />
<input type="hidden" name="delete_id[]" value="' . $row['cases_id'] . '" />
</li>
<li>
<input type="text" name="file[]" size="25" />
<input type="text" name="case[]" size="25" />
<input type="text" name="name[]" size="25" />
<input type="submit" name="delete_case" id="delete_case" value="Delete Case" />
<input type="hidden" name="delete_id[]" value="' . $row['cases_id'] . '" />
</li>
<li>
<input type="text" name="file[]" size="25" />
<input type="text" name="case[]" size="25" />
<input type="text" name="name[]" size="25" />
<input type="submit" name="delete_case" id="delete_case" value="Delete Case" />
<input type="hidden" name="delete_id[]" value="' . $row['cases_id'] . '" />
</li>
Here is the MySQL tables.
CREATE TABLE cases (
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
file VARCHAR(255) NOT NULL,
case VARCHAR(255) NOT NULL,
name VARCHAR(255) NOT NULL,
PRIMARY KEY (id)
);
CREATE TABLE users_cases (
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
cases_id INT UNSIGNED NOT NULL,
user_id INT UNSIGNED NOT NULL,
PRIMARY KEY (id)
);
