Form doesn't submit all fields - php

Question

I have a pretty huge form which I am able to extend dynamically with JavaScript. In this form I am having different DataSets with about 50 fields to submit each. When I submit the form I am running through a for loop from 0 to 100 to check which fields are set. So I create the HTML like this:
<form id = "formUpdate" role="form" action="index.php?action=update" method="post">
<table id="table" class="table table-hover"><thead>
<tr>
<th> Head1
<th> Head2
<th> Head3
<th> Head4
<th> Head5
<th> Head6
<th> ...
<tbody>
<?php
for ($i=0;$i<$dataSets;$i++){ ?>
<tr>
<td style="text-align: center; vertical-align: middle;"><label><?php echo $test[$i]['1']; ?> </label></td>
<td style="text-align: center; vertical-align: middle;"> <input required class="form-control formsUser" form="formUpdate" name="fieldA<?php echo $test[$i]['2']; ?>" value=""></input>
<td style="text-align: center; vertical-align: middle;"> <textarea style="height:34px" class="form-control formsUser" form="formUpdate" name="fieldB<?php echo $test[$i]['3'];?>" required></textarea>
<td style="text-align: center; vertical-align: middle;"> <input class="form-control formsUser" form="formUpdate" name="fieldC<?php echo $test[$i]['4']; ?>" required value=""></input>
<td style="text-align: center; vertical-align: middle;"> <input class="form-control formsUser" form="formUpdate" name="fieldD<?php echo $test[$i]['5']; ?>" required value=""></input>
<td style="text-align: center; vertical-align: middle;"> <input class="form-control formsUser" form="formUpdate" name="fieldE<?php echo $test[$i]['6']; ?>" value=""></input>
</tr>
<?php } ?>
</table>
<button class="btn btn-success" form="formUpdate" type="submit"> Submit </button>
</form>
PHP:
public function update(){
print_r($_REQUEST);
for ($i=0;$i<100;$i++){
$string = "fieldA".$i;
if (isset($_POST[$string])){
// set the other _POSTS
}
else {
//do something different
}
}
}
But this works only for the first 10 Datasets. When I call print_r($_REQUEST); it also just contains the content of the fields of the first 10 Datasets. I read about the limit of max_input_vars in the php.ini and increased this value, but nothing has changed. Besides I shouldn't reach the default value of 1,000 with my data. I also tried changing the value of max_input_nesting_level, memory_limit and post_max_size.

OMG. Got the Problem. I am using DataTables and when submitting the form, the table is redrawed showing the first 10 Datasets only...sorry for that guys and thanks for your help :)
