How to using If else for conditional <select> option in PHP? - php

Question

The scenario is, I have 3 level user (Employer,Manager,Cashier), if the employer login the page, the employer just can see Manager and Cashier option in the select box;if the manager login the page, the manager just can see Cashier option in the select box
User level number I have stored in this variable $user_level, when the user login the id of the user will record in this variable $user_level. In the user value I have set the user level Employer id is 1, Manager id is 2, Cashier id is 3. For example, when the user level 1 (Employer) login the page, the option just can show Manager and Cashier option.When the user level 2 (Manager) login the page, the option just can Cashier option. My problem is how to change below the coding to if/else for conditional option ?
I have declared $user_level = $row['user_level'];
Below is my code:
<div class="form-group col-lg-6">
<label class="control-label col-lg-4">Position<span style="color:red;"> *</span></label>
<div class="col-lg-7">
<select class="form-control required" id="position" name="position">
<option value="">Please Select</option>
<option value="2">Manager</option>
<option value="3">Cashier</option>
</select>
<br>
</div>
</div>
Below the coding is check the user login current position(user level number),this part in the future will hidden:
<div class="form-group col-lg-6">
<label class="control-label col-lg-4">Current Login User Level<span style="color:red;"> *</span></label>
<div class="col-lg-7">
<input disabled type="text" class="form-control required" id="user_level" name="user_level" value="<?php echo $user_level; ?>">
</div>
</div>
Below is my output example:
Hope someone can guide me to solve this problem. Thanks a lot.

You can add if-else logic inline with the options:
<?php if($user_level != 3) { ?>
<div class="form-group col-lg-6">
<label class="control-label col-lg-4">Position<span style="color:red;"> *</span></label>
<div class="col-lg-7">
<select class="form-control required" id="position" name="position">
<option value="">Please Select</option>
<?php if($user_level == 1) { ?>
<option value="2">Manager</option>
<?php } ?>
<?php if($user_level == 1 || $user_level == 2) { ?>
<option value="3">Cashier</option>
<?php } ?>
</select>
<br>
</div>
</div>
<?php } ?>
