Codeigniter 3: Insert array form to database - php

Question

I'm new with Codeigniter and I'm having some trouble inserting arrays into my database. An error kept popping out that I can't insert array to my database.
Here's my HTML form:
<?= form_open('profile/profile_submit'); ?>
<table class="table table-hover table-striped table-responsive">
<thead>
<tr>
<th id="headCheckHide"></th>
<th><center>Name</center></th>
<th><center>Date of Birth</center></th>
<th><center>Occupation</center></th>
<th><center>Educ. attainment</center></th>
</tr>
</thead>
<tbody id="sibTable">
<tr class="product-item">
<td>
<input type="text" class="form-control form-input" name="siblingName[]">
</td>
<td>
<input type="text" class="form-control form-input" name="siblingBirthDate[]">
</td>
<td>
<input type="text" class="form-control form-input" name="siblingOccupation[]">
</td>
<td>
<select class="form-control form-input" name="siblingEducAttainment[]" >
<option value="" selected>-Please select-</option>
<option value="less than high school">less than high school</option>
<option value="Some college but no degree">Some college but no degree</option>
<option value="Associates Degree">Associates Degree</option>
<option value="Elementary Graduate">Elementary Graduate</option>
<option value="Secondary Graduate">Secondary Graduate</option>
<option value="College Graduate">College Graduate</option>
<option value="Master's Degree">Master's Degree</option>
<option value="Professional Degree">Professional Degree</option>
<option value="Doctorate Degree">Doctorate Degree</option>
</select>
</td>
</tr>
</tbody>
</table>
<?= form_submit('submit','Save', 'class="btn btn-outline-primary waves-effect"');?>
<?php echo form_close();?>
My Controller for the form
public function profile_submit(){
$siblings=array(
'name' => $this->input->post('siblingName'),
'birthDate' => $this->input->post('siblingBirthDate'),
'occupation' => $this->input->post('siblingOccupation'),
'educAttainment' => $this->input->post('siblingEducAttainment')
);
$this->profile_model->submit_profile($siblings);
redirect('profile','refresh'); //name of the html file
}
My model for (profile_model.php)
function submit_profile($siblings){
$this->db->insert('tbl_st_profile_sibling',$siblings);
}
this is my model with the error: can't insert array into database.
Can anyone please help? thank you.

Answer 1

I think you need to insert multiple input data at a time with the same name, don't worry please follow my instructions as given below
Changes in Controller:
public function profile_submit(){
$submit_status = $this->profile_model->submit_profile();
if( $submit_status == "TRUE"){
redirect('profile','refresh'); //name of the html file
}else{
// Do Something else..
}
}
Changes in Model:
function submit_profile(){
$siblingsCount = count($this->input->post('siblingName'));
if($siblingsCount != null){
$itemValues=0;
$query = "INSERT INTO tbl_st_profile_sibling(name,birthDate,occupation,educAttainment) VALUES ";
$queryValue = "";
for($i=0;$i<$siblingsCount;$i++) {
$name = $this->input->post('name');
$birthDate = $this->input->post('birthDate');
$occupation = $this->input->post('occupation');
$educAttainment = $this->input->post('educAttainment');
if(!empty($name[$i])) {
$itemValues++;
if($queryValue!="") {
$queryValue .= ",";
}
$queryValue .= "('" . $name[$i] . "', '" . $birthDate[$i] . "', '" . $occupation[$i] . "', '" . $educAttainment[$i] . "')";
}
}
$sql = $query.$queryValue;
if($itemValues!=0) {
if (!$this->db->query($sql)) {
echo "FALSE";
}else {
echo "TRUE";
}
}
}
}
I hope this may help you...Thanks!

If you need to store array data into DB you need to use loops to insert one.
function submit_profile($siblings){
foreach($siblings['name'] as $key => $siblingName) {
$dataToSave = array(
'name' => $siblingName,
'birthDate' => $siblings['siblingBirthDate'][$key],
'occupation' => $siblings['siblingOccupation'][$key],
'educAttainment' => $siblings['siblingEducAttainment'][$key]
);
$this->db->insert('tbl_st_profile_sibling', $dataToSave);
}
}
UPDATE : Even you can use insert_batch to skip insertion in loop
function submit_profile($siblings){
foreach($siblings['name'] as $key => $siblingName) {
$dataToSave[] = array(
'name' => $siblingName,
'birthDate' => $siblings['siblingBirthDate'][$key],
'occupation' => $siblings['siblingOccupation'][$key],
'educAttainment' => $siblings['siblingEducAttainment'][$key]
);
}
$this->db->insert_batch('tbl_st_profile_sibling', $dataToSave);
}

Answer 3

The issue is not with the array you are saving into database the actual issue is with the post fields thy are in array format siblingName[]. So you need to convert then into strings so that this can be saved easily.
convert the array into coma separated list and then save in database.
$siblingName = implode(",",$_POST['siblingName']);
$siblingBirthDate= implode(",",$_POST['siblingBirthDate']);
$siblingOccupation= implode(",",$_POST['siblingOccupation']);
$siblingEducAttainment= implode(",",$_POST['siblingEducAttainment']);
$siblings=array(
'name' => $siblingName,
'birthDate' => $siblingBirthDate,
'occupation' => $siblingOccupation,
'educAttainment' => $siblingEducAttainment
);

<input type="hidden" name="count" value="<?php echo count($var); ?>" />
for($i=0;$i < count($var);$i++)
{
<tr class="product-item">

}
$count = $this->input->post('count');
for($i=0;$i < $count;$i++)
{
$siblings=array(
