please help me get through with this.
Everytime I update data from database there is '\' added before the single quote.
For example I have an input that has a value=I'm ok after updating there is '\' will be added.
Sample code from my Model
function update_questionnaire() {
$Cid1 = $this->input->post('Cid1');
$Cid2 = $this->input->post('Cid2');
$Cdata = array(
array(
'choices_id' => $Cid1,
'questionnaire_id_fk' => $Qid,
'choices' => $choice1
),
array(
'choices_id' => $Cid2,
'questionnaire_id_fk' => $Qid,
'choices' => $choice2
)
);
$question = $this->db->escape_like_str($this->input->post('question', TRUE));
$this->db->update_batch('choices', $Cdata, 'choices_id');
}
And sample code from my Controller
$this->form_validation->set_rules('choice1', 'Choice 1', 'required|trim');
$this->form_validation->set_rules('choice2', 'Choice 2', 'required|trim');
And sample code from my View
<?php
$i=0;
foreach ($query as $row):
$i++;
echo '<input type="text" name="choice' . $i . '" id="choice_' . $row->choices_id . '" value="' . trim_slashes($row->choices) . '" class="form-control"/>';
endforeach;
?>

I have to following foreach loop
$data = array(
"success" => false,
"results" => array()
);
foreach ($cart->get_contents() as $item) {
$data['items'][] = array(
'description' => urlencode($item['name']),
'amount' => urlencode($item['price']),
'quantity' => urlencode($item['qty'])
);
}
$data['success'] = true;
Now I would like to for the following for each item
<input type="hidden" name="' . $field . '" value="' . htmlentities($value) . '">
where the $field would be the item description, and the htmlentities($value) would be the corresponding value from the loop.
Any help welcome as I am not sure where to start, sorry if this is very obvios
I think (if I understand you) that you can achieve this like:
$data = [
'success' => false,
'items' => [] // Probably itemsm not results??
];
foreach ($cart->get_contents() as $item) {
$data['items'][] = array(
'description' => urlencode($item['name']),
'amount' => urlencode($item['price']),
'quantity' => urlencode($item['qty'])
);
}
$data['success'] = true;
foreach ($data['items'] as $item) {
echo "<input type='hidden' name='" . $item['description'] . "'' value='" . htmlentities($item['amount']) . "'>";
}
I also updated the code a little.
I need to return my collection into an array that Chatfuel, and specifically Messenger, understands. When calling User::get(), I get a collection of all the users, but I need to map it out to the JSON array that Chatfuel expects.
I've previously (when I was using raw PHP and no framework), done it like so:
<?php
$det = array();
while ($row = mysqli_fetch_assoc($results)) {
$row_array['title'] = $row['book-title'] . " | " . $row['edition'] . " Edition";
$row_array['image_url'] = $row['image-url'];
$row_array['subtitle'] = $row['author'];
if (!empty($_SESSION['loggedinuniid'])) {
$urllink = "https://example.com/textbook/?isbn=" . $row['isbn'] . '&uni=' . $_SESSION['loggedinuniid'] . '&submit';
} else {
$urllink = "https://example.com/textbook/?isbn=" . $row['isbn'] . '&submit';
}
$row_array['item_url'] = $urllink;
if ($row['rrs'] == 0) {
$row_array['buttons'] = array(array('type' => 'web_url', 'url' => $urllink, 'title' => 'See Textbook'));
} else {
$row_array['buttons'] = array(array('type' => 'web_url', 'url' => $urllink . '#selling', 'title' => 'Buy Textbook (' . $row['rrs'] . ')'));
}
array_push($det, $row_array);
}
$row_array['title'] = "Find Textbooks on example";
$row_array['subtitle'] = "Search for textbooks sold by your classmates at uni!";
$row_array['image_url'] = "";
$urllink = "https://example.com/";
$row_array['item_url'] = $urllink;
$row_array['buttons'] = array(array('type' => 'web_url', 'url' => $urllink, 'title' => 'See All Textbooks'));
array_push($det, $row_array);
$final = array(
'messages' => array(
array("attachment" => array(
"type" => "template", "payload" => array(
"template_type" => "generic", "elements" => $det,
),
),
),
array("text" => "Hope this helps! You can also always search on example.com!"),
),
);
$post_data = json_encode($final);
exit($post_data);
And, while it got the job done, it isn't really readable or clean.
What's the best way to take an existing collection, and map it out to a custom key/value array I need?
when i run this query i have the result in the right why but name and the father name repeated in all lines . i want it just one time . i put for example the 1773 id number to test it .
<?
$query = mysql_query("
SELECT *
FROM students,grades,subjects
WHERE
students.id_students = grades.id_students AND
grades.id_subjects = subjects.id_subjects AND
students.id_students = 1773 ;
");
while ($row = mysql_fetch_assoc($query)
){
$id_students = $row['id_students'];
$firstname = $row['firstname'];
$surename = $row['surename'];
$father = $row['father'];
$marks = $row['marks'];
$class = $row['class'];
$name = $row['name'];
echo "$firstname" . "$surename";
echo "$marks" ." " . "$name" ;
echo "<br>";
echo "$class";
}
?>
Use just one table in FROM clause and for others use JOIN.
SELECT s.*,
g.*,
su.*
FROM students s
JOIN grades g
ON g.id_students = s.id_students
JOIN subjects su
ON su.id_subjects = g.id_subjects
WHERE s.id_students = 1773
Due to the previous answer which will be deleted, this should be what you need. $data array is the same as you get from database.
<?php
$data = array(
0 => array(
'id_students' => 1,
'firstname' => 'Fuad',
'surename' => 'Bro',
'father' => 'fathers name',
'marks' => 30,
'class' => 1,
'name' => 'itd'
),
1 => array(
'id_students' => 1,
'firstname' => 'Fuad',
'surename' => 'Bro',
'father' => 'fathers name',
'marks' => 120,
'class' => 1,
'name' => 'biography'
),
2 => array(
'id_students' => 1,
'firstname' => 'Fuad',
'surename' => 'Bro',
'father' => 'fathers name',
'marks' => 120,
'class' => 1,
'name' => 'informatic'
)
);
$last_name = '';
foreach ($data as $row) {
if ($row['firstname'] != $last_name) {
echo '<b>' . $row['firstname'] . ' ' . $row['surename'] . ' (father: ' . $row['father'] . ')</b><br>';
}
echo 'class: ' . $row['class'] . '<br>';
echo 'subject name: ' . $row['name'] . '<br>';
echo 'marks: ' . $row['marks'] . '<br><br>';
$last_name = $row['firstname'];
}
/*
output:

class: 1
subject name: itd
marks: 30

I need help to get the data from my checkbox-group with multidimensional array options to reflect in my post page(single.php code). Radio type is working well but the checkbox-group type is not.

Please help!.. I am not a programmer hope you can share me an answer in much details.Thank you in advance!
All what you need is point an array using var_dump($array) to check where and what data you need from arrays fields.
Second you need to get foreach() function. For example you want grab an array of data:
'priority' => 'high', should be as example:
echo $meta_box["priority"] which will result as value of array: high
If you are not sure and not familiar with array use as simple:
foreach ($meta_box as $arr)
{
var_dump($arr);
#then play and manipulate how to grab a fields a data:
foreach ($arr["fields"][""] as $fa)
{
var_dump($fa["name"]);
var_dump($fa["desc"]);
var_dump($fa["desc"]);
}
#...
}
Learn how to grab via var_dump() if you unsure with array of data.
Payment Processors LR STP EgoP
echo $meta_box["fields"][""]["name"];
Than you need grab a data of an array:
foreach ($meta_box["fields"][""]["options"] as $options)
{
foreach ($options as $options_key)
{
foreach ($options_key as $opt_val)
{
$result .= ' '.$opt_val;
}
}
}
I am using codeigniter update_batch function.
I want to pass an array as the third parameter (where clause) to update_batch.
$data = array(
array(
'title' => 'My title' ,
'name' => 'My Name 2' ,
'date' => 'My date 2'
),
array(
'title' => 'Another title' ,
'name' => 'Another Name 2' ,
'date' => 'Another date 2'
)
);
Instead of this:
$this->db->update_batch('mytable', $data, 'title');
I want to do this:
$this->db->update_batch('mytable', $data, array('title','name'));
So multiple where conditions added.
Is this possible?
You could do this by creating your method for batch update in your model Test_model for example because Codeigniter does not supports multiple where condition in native update_batch, so example below:
public function update_batch_custom($table_name, $data, $indexes) {
if (empty($data) || empty($indexes)){
return 'Data or indexes must not be empty';
}
$db = $this->load->database('test_db', TRUE);
$sql = 'UPDATE ' . $table_name . ' SET ' . "\n";
//columns on which is done actual update
$columns = [];
foreach ($data[0] as $key => $value) {
if (!in_array($key, $indexes)){
$columns[] = $key;
}
}
/*
* forming WHEN .. THEN sql parts and WHERE condition
*/
$parts = [];
$where = [];
foreach ($data as $row) {
foreach ($columns as $column) {
$sql_part = ' WHEN (';
foreach ($indexes as $index) {
$sql_part .= $index . '= \''.$row[$index] . '\' AND ';
$where[$index][] = $row[$index];
}
$sql_part = substr($sql_part, 0, -4);
$sql_part .= ') THEN \'' . $row[$column] . '\'';
$parts[$column][] = $sql_part;
}
}
/*
* connecting WHEN .. THEN parts for each column to be updated
*/
foreach ($columns as $column) {
$sql .= $column .'= CASE ';
foreach ($parts[$column] as $sql_part) {
$sql .= $sql_part;
}
$sql .= ' ELSE ' . $column . ' END,';
}
/*
* adding WHERE part
*/
$sql = substr($sql, 0, -1);
$sql .= ' WHERE ';
foreach ($indexes as $index) {
if ( count($where[$index]) > 0){
$unique_where = array_unique($where[$index]);
$sql .= $index . ' IN (\'' . join('\',\'', $unique_where) . '\') AND ';
}
}
$sql = substr($sql, 0, -4);
$sql .= ';';
return $db->query($sql);
}
You can use below code to update your data:
$this->db->update("TableName",[dataarray],[where condition array]);
This update_batch function does not allow WHERE parameter, but you can try splitting it before calling the function.
Try this:
$data = array(
array(
'title' => 'My title' ,
'name' => 'My Name 2' ,
'date' => 'My date 2'
),
array(
'title' => 'Another title' ,
'name' => 'Another Name 2' ,
'date' => 'Another date 2'
)
);
$this->db->where('name','My Name 2');
$this->db->update_batch('mytable', $data, 'title');
Controller:
$chunk1 = array_chunk($data,100);
for($i=0;$i < count($chunk1);$i++) {
$this->upload_model->update_data($chunk1[$i],'My Name 2');
}
Model:
public function update_data($data='',$name=''){
$this->db->where('name',$name);
$this->db->update_batch('mytable', $data, 'title');
}
Remember, my WHERE parameter is a static value.
You could always do this:
$data = array(
array(
'title' => 'My title' ,
'name' => 'My Name 2' ,
'date' => 'My date 2'
),
array(
'title' => 'Another title' ,
'name' => 'Another Name 2' ,
'date' => 'Another date 2'
)
);
$this->db->where(array('title' => 'title', 'name' => 'name'));
$this->db->update_batch('mytable', $data);
Not tested.
UPDATE This lacks the required where parameter in update_batch().
