Call for the wordpress text field - php

Question

I am working in an existing theme from my company. They have a special page template. This template uses custom fields you can fill in, they then get displayed on the page.
The general text field that you see when editing a page is not shown on the page however. (it is in the dashboard environment.) This is what the page template looks like:
<?php get_header() ?>
<?php the_post() ?>
<!-- start content -->
<div id="content">
<div class="col left">
<?php dynamic_sidebar( 'left-widgets' ); ?>
</div>
<h1 class="mobiletitle" style="text-align:center;"><?php the_title() ?> </h1>
<div id="center">
<div class="two-col">
<?php
if( get_field('slider') )
{ ?>
<div class="rslides_container">
<ul class="rslides" id="slider1">
<?php while( has_sub_field("slider") )
{
$variable = get_sub_field('image'); ?>
<li><img src="<?php echo $variable;?>" alt="Magic Stables"></li>
<?php } ?>
</ul>
</div>
<?php } ?>
<h1 class="maintitle" style="text-align:center;"><?php the_title() ?> </h1>
<div class="horseinfo">
<table>
<?php if(get_field('naam_paard')) { ?>
<tr>
<td><?php if(ICL_LANGUAGE_CODE=='nl') { ?>
Naam:
<?php } else { ?>
Name:
<?php } ?></td>
<td><?php the_field('naam_paard'); ?></td>
</tr>
<?php } ?>
<?php if(get_field('afstamming')) { ?>
<tr>
<td><?php if(ICL_LANGUAGE_CODE=='nl') { ?>
Afstamming:
<?php } else { ?>
Breed:
<?php } ?></td>
<td><?php the_field('afstamming'); ?></td>
</tr>
<?php } ?>
<?php if(get_field('geslacht')) { ?>
<tr>
<td><?php if(ICL_LANGUAGE_CODE=='nl') { ?>
Geslacht:
<?php } else { ?>
Gender:
<?php } ?></td>
<td><?php the_field('geslacht'); ?></td>
</tr>
<?php } ?>
<?php if(get_field('geboortejaar')) { ?>
<tr>
<td><?php if(ICL_LANGUAGE_CODE=='nl') { ?>
Geboortejaar:
<?php } else { ?>
Year of Birth:
<?php } ?></td>
<td><?php the_field('geboortejaar'); ?></td>
</tr>
<?php } ?>
<?php if(get_field('geboortejaarkleur')) { ?>
<tr>
<td><?php if(ICL_LANGUAGE_CODE=='nl') { ?>
Geboortejaarkleur:
<?php } else { ?>
Birth color:
<?php } ?></td>
<td><?php the_field('geboortejaarkleur'); ?></td>
</tr>
<?php } ?>
<?php if(get_field('stokmaat')) { ?>
<tr>
<td><?php if(ICL_LANGUAGE_CODE=='nl') { ?>
Stokmaat:
<?php } else { ?>
Height:
<?php } ?></td>
<td><?php the_field('stokmaat'); ?></td>
</tr>
<?php } ?>
<?php if(get_field('fokker_naam')) { ?>
<tr>
<td><?php if(ICL_LANGUAGE_CODE=='nl') { ?>
Fokker:
<?php } else { ?>
Breeder:
<?php } ?></td>
<td><?php the_field('fokker_naam'); ?></td>
</tr>
<?php } ?>
<?php if(get_field('fokker_plaats')) { ?>
<tr>
<td><?php if(ICL_LANGUAGE_CODE=='nl') { ?>
Fokker plaats:
<?php } else { ?>
Breeding place:
<?php } ?></td>
<td><?php the_field('fokker_plaats'); ?></td>
</tr>
<?php } ?>
<?php if(get_field('overig')) { ?>
<tr>
<td><?php if(ICL_LANGUAGE_CODE=='nl') { ?>
Overig:
<?php } else { ?>
Other:
<?php } ?></td>
<td><?php the_field('overig'); ?></td>
</tr>
<?php } ?>
</table>
</div>
<br><br>
<?php if(the_content()) { ?>
<div class="one-col">
<?php the_content() ?>
</div>
<?php } ?>
<?php if(get_field('linkerkolom')) { ?>
<div class="two-col-1">
<?php the_field('linkerkolom'); ?>
</div>
<div class="two-col-2">
<?php the_field('rechterkolom'); ?>
</div>
<?php } ?>
</div>
</div>
<div class="col right">
<?php dynamic_sidebar( 'right-widgets' ); ?>
</div>
<?php get_footer() ?>
I see that with this line you make the text from a custom form appear:
<?php the_field('fokker_naam'); ?>
Now, how do I get the normal field to appear on the page again? What is the name of this field?
I need to use this field because I would like to use the editor, to create font styles and such.

Answer 1

The main post content is accessed via the_content() function:
<?php the_content(); ?>
