I have store labels and numeric values of same form in two arrays, pass these arrays using AJAX to php. now I want to store each array in two different fields of the same table mysql.
var arr = [];
var arr1 = [];
$('.cat').each(function() {
arr.push($(this).text());
});
$('.cat_value').each(function() {
arr1.push($(this).val());
});
$.ajax({
url:'rs_insert.php',
data:{categories: arr, cat_values:arr1},
type:'POST',
success:function() {
alert("data has been sent");
document.getElementById('exampleModal1').style.display = "none";
}
});
php file
$con=mysqli_connect("localhost","root","","test");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$values = array();
foreach($_POST['categories'] as $key => $name) {
$values[] = $name;
}
$sql1 = "INSERT INTO rs (Category) VALUES ";
foreach($values as $cat) {
$sql1 .= "('" . $cat . "'),";
}
$sql1_trimmed = rtrim($sql1,',');
////
$values1 = array();
foreach($_POST['cat_values'] as $key => $value) {
$values1[] = $value;
}
$sql2 = "INSERT INTO rs (Value) VALUES ";
foreach($values1 as $val) {
$sql2 .= "('" . $val . "'),";
}
$sql2_trimmed = rtrim($sql2,',');
if (!mysqli_query($con,$sql1_trimmed)) {
die('Error: ' . mysqli_error($con));
}
if (!mysqli_query($con,$sql2_trimmed)) {
die('Error: ' . mysqli_error($con));
}
the problem is, it does not inserted values parrallel. first it insert values in category field with 0 under value field. the filled value field with blank categories name.
you can try this:
$con=mysqli_connect("localhost","root","","test");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$values = array();
foreach($_POST['categories'] as $key => $name) {
$values[] = $name;
}
////
$values1 = array();
foreach($_POST['cat_values'] as $key => $value) {
$values1[] = $value;
}
$sql1 = "INSERT INTO rs (Category,Value) VALUES ";
for($i=0;$i<count($values);$i++) {
$sql1 .= "('" . $values[$i] . "','". $values1[$i] ."'),";
}
$sql1_trimmed = rtrim($sql1,',');
if (!mysqli_query($con,$sql1_trimmed)) {
die('Error: ' . mysqli_error($con));
}

I have been retrieving call logs from a cdr and dumping them into a database in MySQL. Of late the database crashes and the was giving me duplicates and junk characters so i modified to the below code.
modified code
$file1 = file_get_contents('file:///C:/Users/thy/Desktop/2011_0419_1531_v3.12R/cdr/'.$newname, FILE_USE_INCLUDE_PATH);
$arr1 = explode("\n", $file1);
foreach ($arr1 as $key => $value) {
$colArray = [];
$colArray['id'] = null;
$colArray['hashkey'] = md5(uniqid(rand(), true));
$split = explode(";", $value);
foreach ($split as $key => $val) {
# code...
$arr = (explode('=', $val));
$field = 'ch';
$item = '0';
$field = $arr[0];
$item = $arr[1];
$item = str_replace(str_split(')(\/'), '', $item);
$colArray[$field] = $item;
}
$columns = implode(', ', array_keys($colArray));
$values = implode(', ', $colArray);
$sql = "INSERT INTO `call`.`logs` (" . $columns . ") VALUES (" . $values . ")";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
}
the above code keeps giving me errors
Error: INSERT INTO call.logs (id, hashkey, ) VALUES (,
797d8782a433b30e196fafc0ce01d09b, )You have an error in your SQL

Original code is below (the one i modified it from)
$file1 = file_get_contents('file:///C:/Users/thy/Desktop/2011_0419_1531_v3.12R/cdr/'.$newname, FILE_USE_INCLUDE_PATH);
$arr1 = explode("\n", $file1);
$data1 = array();
foreach ($arr1 as $key => $value) {
$split = explode(";", $value);
$keys = md5(uniqid(rand(), true));
//insert key to identify call.
$sql = "INSERT INTO `call`.`logs` (`id`, `hashkey`) VALUES (NULL, '{$keys}')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
foreach ($split as $key => $val) {
# code...
$arr=(explode('=', $val));
$field='ch';
$item='0';
$field=$arr[0];
$item=$arr[1];
echo $field . " --";
echo "<br/>";
echo $item;
//sql
$sql = "UPDATE logs SET {$field}='{$item}' WHERE hashkey='{$keys}'";
if ($conn->query($sql) === TRUE) {
echo "Record updated successfully";
} else {
echo "Error updating record: " . $conn->error;
}
echo "done";
//$conn->close();
} echo "<br/>";
}

I think the problem is with the generated/devised INSERt statement
INSERT INTO call.logs (" . $columns . ") VALUES (" . $values . ")";
There is an extra comma getting appended without column name?
If id is an autoincremental field. Try this:
INSERT INTO call.logs (id, hashkey) VALUES (default, '797d8782a433b30e196fafc0ce01d09b')
I want to use single for each for two array.
array 1 : has path of images (path is dynamic as per user need)
array 2: has values description field of each image (description is dynamic as per user need)
I want to insert both array in sql table using only one sql statement.
<?php $sql="INSERT INTO posts(title,description,category,createdBy,pictureURL,CreatedAt) VALUE ('$title',
'$description','$category','$creatdby','Admin/PostImages/$finalpath',now());";
$result = mysqli_query($conn,$sql);
if($result)
{
$upload_directory = 'PostImages/';
$field_values_array = $_REQUEST['desc'];
$x=0;
foreach($field_values_array as $value1){
foreach ( $_FILES['photo']['name'] AS $key => $value ){
//Move file to server directory
if(move_uploaded_file($_FILES["photo"]["tmp_name"][$x], $upload_directory . $_FILES["photo"]["name"][$x])){
$finalpath=$upload_directory . $_FILES["photo"]["name"][$x];
}
if (isset($_SESSION['p_id'])){
$p_id = $_SESSION["p_id"];
}
$sql1="INSERT INTO `postimages`(`p_id`,`description`, `img_path`) VALUES ('$p_id','$value1','$finalpath')";
$result1 = mysqli_query($conn,$sql1);
$x++;
}
}
header("Location: uploadpost_test.php");
}
else
{
echo "Error: " . $sql . "<br>" . $conn->error;
} ?>
I refactor and clean up your codes. Try this.
if(isset($_SESSION['p_id']))
{
$p_id = $_SESSION["p_id"];
}
$values = '';
$next = ',';
$len = count($field_values_array);
foreach($field_values_array as $x=>$value1)
{
if(move_uploaded_file($_FILES["photo"]["tmp_name"][$x], $upload_directory.$_FILES["photo"]["tmp_name"][$x]))
{
$tmp_name = $_FILES["photo"]["tmp_name"][$x];
$finalpath = $upload_directory.$tmp_name;
$next = $x >= $len-1 ? '' : $next;
$values .= "VALUES('$p_id','$value1','$finalpath')".$next;
}
}
$sql1="INSERT INTO `postimages`(`p_id`,`description`, `img_path`) $values";
$result1 = mysqli_query($conn,$sql1);
I have the following code but i am not sure how to check if insert is success. execute returns resource id. I would like to check if success and return all errors on fail.
public function persist()
{
$update = FALSE;
if(!is_array($this->tablePrimaryKey)) {
if(!empty($this->fieldVals[$this->tablePrimaryKey])) {
$update = true;
}
}
if ($update) {
$sql = "UPDATE " . $this->tableName . " SET ";
$binds = [];
foreach ($this->fieldVals as $key=>$val) {
if ($key != $this->tablePrimaryKey) {
if(in_array($key, $this->DATE_IDS)) {
$sql .= '"' . strtoupper($key) . '" = sysdate,';
} else {
$bind = 't_' . $key;
$binds[$bind] = $val;
$sql .= '"' . strtoupper($key) . '" = :' . $bind . ',';
}
}
}
$sql = substr($sql,0,-1);
$sql .= " WHERE " . $this->tablePrimaryKey . " = '" . $this->fieldVals[$this->tablePrimaryKey] ."'";
} else {
$binds = $fields = $date_fields = [];
if(!empty($this->tablePrimaryKey) && !is_array($this->tablePrimaryKey)) {
$this->fieldVals[$this->tablePrimaryKey] = $this->generateNewPrimaryKey();
}
foreach ($this->fieldVals as $key=>$val) {
$bind = ':t_' . $key;
if (in_array($key, $this->DATE_IDS)) {
$date_fields[] = strtoupper($key);
} else {
$binds[$bind] = $val;
$fields[] = strtoupper($key);
}
}
$sql = 'INSERT INTO ' . $this->tableName . '("' . implode('","', $fields);
if(count($date_fields) >0) {
$sql .= '","';
$sql .= implode('","', $date_fields);
}
$sql.='") VALUES (' . implode(',', array_keys($binds));
if(count($date_fields) >0) {
$cnt=0;
foreach($date_fields as $date) {
$cnt++;
if(preg_match('/NULL/i', $this->fieldVals[strtolower($date)], $result)) {
$sql .= ",NULL";
} elseif(isset($this->fieldVals[strtolower($date)])) {
$sql .= ",TO_DATE('" . (new DateTime($this->fieldVals[strtolower($date)]))->format("Y-M-d H:i:s") . "', 'yyyy/mm/dd hh24:mi:ss')";
} else {
$sql .= ",sysdate";
}
}
}
$sql .= ')';
}
$this->oiDb->parse($sql, $binds);
return $this->oiDb->execute();
}
I run $result = $oiRequests->hydrate($reportingRequest)->persist();. $reportingRequest is key,value pair of columns/values. $result contains resource id. $oiRequests is my model.
I have tried
$num_rows = oci_fetch_assoc ($result);
print_r($num_rows);
returns
Warning: oci_fetch_assoc(): ORA-24374: define not done before fetch or execute and fetch in /var/SP/oiadm/docroot/dev/uddins/requestportal/requestportal_ajax.php on line 65
Most of the OCI functions return false on error. This means you can do a simple check on the return value and, if it's false, call oci_error().
For the specific case of checking if an INSERT statement worked you can reference the example code for oci_commit(). The relevant part of that example is duplicated here:
// The OCI_NO_AUTO_COMMIT flag tells Oracle not to commit the INSERT immediately
// Use OCI_DEFAULT as the flag for PHP <= 5.3.1. The two flags are equivalent
$r = oci_execute($stid, OCI_NO_AUTO_COMMIT);
if (!$r) {
$e = oci_error($stid);
trigger_error(htmlentities($e['message']), E_USER_ERROR);
}
Below I have Php code that loops through an array and for each it checks if the value already exists in the database and if not, create it. The code itself is working but the loop itself can be insanely big, maximum of a couple tens thousand iterations.
How can I optimize this code? What to use and how to use. There should be a better way to insert this many times without looping through each individual.
foreach($arr as $value){
$checkID = mysqli_query($cenn, "SELECT item_id from items WHERE item_id = '$value'");
if (!$checkID) {
die("Query '$checkID' failed to execute for some reason");
}else{
if (mysqli_num_rows($checkID) > 0) {
$user = mysqli_fetch_array($checkID);
echo "item_id" . checkID . "exists already";
}
else{
echo "item_id: '$user_id' doesn't exist<br>";
$gw2Api = file_get_contents("https://api.guildwars2.com/v2/items/" . $user_id); //12452 30704
$gw2Api_result = json_decode($gw2Api,true);
/*Here would be some code to determine values that are being inserted*/
if (!array_key_exists("description",$gw2Api_result)) {
$description = 'No description available...';
} else{
if($gw2Api_result['description'] === ''){
$description = "No description available...";
} else {
$description = $gw2Api_result['description'];
}
}
$insertItem = "INSERT INTO items
(item_id, name, description,
AccountBindOnUse, AccountBound,
last_update
)
VALUES ('$user_id', '$gw2Api_result[name]', '$description',
'$AccountBindOnUse', '$AccountBound', CURRENT_TIMESTAMP)";
if ($cenn->query($insertItem) === true) {
echo "New record '$user_id' created successfully";
} else {
echo "Error: " . $sql . "<br>" . $cenn->error;
}
}
}
} // end foreach
The question: How to insert many values, new rows, into mysqli database as fast as possible.
Just use bulk insert.
Collect all the rows for insertion and pass it in one query.
echo 'hi';
if (!empty($arr)) {
echo 'ok';
$values = "'" . implode("', '", $arr) . "'";
$qExistingItemIds = mysqli_query($cenn, "SELECT item_id from items WHERE item_id IN($values)");
$existingItemIds = [];
while ($existingItemId = mysqli_fetch_array($qExistingItemIds)) {
$existingItemIds[] = $existingItemId['item_id'];
}
$arr = array_diff($arr, $existingItemIds);
$inserts = array();
$i = 0;
$ic = count($arr);
foreach ($arr as $value) {
$i++;
echo "item_id: $value doesn't exist<br>";
$gw2Api = file_get_contents("https://api.guildwars2.com/v2/items/" . $value); //12452 30704
$gw2Api_result = json_decode($gw2Api,true);
/*Here would be some code to determine values that are being inserted*/
if (!array_key_exists("description", $gw2Api_result)) {
$description = 'No description available...';
} else {
if ($gw2Api_result['description'] === '') {
$description = "No description available...";
} else {
$description = $gw2Api_result['description'];
}
}
$inserts[] = "
('$value', '$gw2Api_result[name]', '$description', '$AccountBindOnUse', '$AccountBound', CURRENT_TIMESTAMP)
";
if ($i == 50 OR $i == $ic) {
$inserts = implode(",", $inserts);
$insert = "
INSERT INTO items
(item_id, name, description, AccountBindOnUse, AccountBound, last_update)
VALUES
$inserts
";
if ($cenn->query($insert) === true) {
echo 'great';
echo "New records created successfully";
} else {
echo "Error: " . $sql . "<br>" . $cenn->error;
}
$ic -= 50;
$i = 0;
$inserts = array();
}
}
}
so now we have only 2 queries. not thousands
details about bulk insert:
http://www.geeksengine.com/database/data-manipulation/bulk-insert.php
If you use prepared statement you should reduce the round trips to the database server and only compile and optimise each query once instead of Number_of_inputs * 2 queries. This should reduce the workload.
I would be very interested to know by how much.
$sql = "SELECT item_id from items WHERE item_id = ?";
$db_select = $cenn->prepare($sql);
if ( ! $db_select ) {
echo $cenn->error;
exit;
}
$sql_insert = "INSERT INTO items
(item_id, name, description,
AccountBindOnUse, AccountBound, last_update)
VALUES (?, ?, ?, ?, ?, CURRENT_TIMESTAMP)";
$db_insert = $cenn->prepare($sql);
if ( ! $db_insert ) {
echo $cenn->error;
exit;
}
foreach($arr as $value){
$db_select->bind_param('i', $value);
$res = $db_select->execute()
if ( $res === FALSE ) {
echo $cenn->error;
exit;
}
if ($db_select->num_rows > 0) {
// dont bother fetching data we already know all we need to
$user = $db_select->free();
echo "item_id $value exists already";
} else {
echo "item_id: $value doesn't exist<br>";
$gw2Api = file_get_contents("https://api.guildwars2.com/v2/items/" . $value);
$gw2Api_result = json_decode($gw2Api,true);
if ( ! array_key_exists("description",$gw2Api_result)
|| $gw2Api_result['description'] === '') {
$description = 'No description available...';
} else{
$description = $gw2Api_result['description'];
}
$db_insert->bind_param('issss', $value, $gw2Api_result[name],
$description, $AccountBindOnUse,
$AccountBound)
if ($cenn->query($insertItem) === true) {
echo "New record $value' created successfully";
} else {
echo "Error: " . $sql_insert . "<br>" . $cenn->error;
}
}
} // end foreach
I have this function
function updateDbRecord($db, $table, $carry, $carryUrl) {
mysql_select_db($db) or die("Could not select database. " . mysql_error());
$resultInsert = mysql_query("SHOW COLUMNS FROM " . $table . " WHERE Field NOT IN ('id')");
$fieldnames=array();
if (mysql_num_rows($resultInsert) > 0) {
while ($row = mysql_fetch_array($resultInsert)) {
$fieldnames[] = $row['Field'];
$arr = array_intersect_key( $_POST, array_flip($fieldnames) ); #check if value is null otherwise do not INSERT
}
}
$set = "";
foreach($arr as $key => $v) {
$val = is_numeric($v) ? $v : "'" . $v . "'";
$set .= $key . '=' . $val . ', ';
}
$sql = sprintf("UPDATE %s SET %s WHERE id='%s'", $table, $set, $_POST['id']);
mysql_query($sql);
if ($carry == 'yes') {
redirect($carryUrl.'?id='.$_REQUEST['id']);
} else { echo "Done!"; }
echo $sql;
}
It outputs for example: UPDATE projects SET project_name='123', project_bold='123', project_content='123', WHERE id='12'
The last comma before where is preventing it from working. Is there a way of avoiding this? Im aware of the function implode, however I am not sure how to employ it in this situation.
Yes,
$sql = substr($sql,'',-1);
I would use
$sql = rtrim($sql, ',');
Either that or instead of appending to a string, append to an array and use implode.
function updateDbRecord($db, $table, $carry, $carryUrl) {
mysql_select_db($db) or die("Could not select database. " . mysql_error());
$resultInsert = mysql_query("SHOW COLUMNS FROM " . $table . " WHERE Field NOT IN ('id')");
$fieldnames=array();
if (mysql_num_rows($resultInsert) > 0) {
while ($row = mysql_fetch_array($resultInsert)) {
$fieldnames[] = $row['Field'];
$array = array_intersect_key( $_POST, array_flip($fieldnames) ); #check if value is null otherwise do not INSERT
}
}
foreach ($array as $key => $value) {
$value = mysql_real_escape_string($value); // this is dedicated to #Jon
$value = "'$value'";
$updates[] = "$key = $value";
}
$implodeArray = implode(', ', $updates);
$sql = sprintf("UPDATE %s SET %s WHERE id='%s'", $table, $implodeArray, $_POST['id']);
mysql_query($sql);
