控制器中的2个按钮

这是我的问题'如果(!empty($_POST['btn_editinventory]))'正在工作，但如果我点击btndeleteinventory，它也将执行我的btneditinventory中的代码。有人知道我将如何纠正我的条件在我的控制器如果你有两个按钮在视图中像这样:

    <input type="button" value="Edit" name="btn_editinventory" id="btn_editinventory" onclick="validate_editinventory();"/>
   <input type="button" value="Delete" name="btn_deleteinventory" id="btn_deleteinventory" onclick="validate_deleteinventory();"/>

提前感谢您的帮助!:)

这是我的观点

    <link rel="stylesheet" type="text/css" href="<?php echo base_url('assets/css/mystyle.css') ?>">
<div id="content">
<form action="edit_delete_others2" method="POST" id='frm_otherequips2' name="frm_otherequips2">
    <fieldset id="edit_other">
        <legend>Inventory Details</legend>
        <table>
            <tr>
                <?php $otherequips = $other2->Equipment;
                      $otherdesc = $other2->ItemDescription;
                      $otherID = $other2->ID;
                      $otherserialnum = $other2->SerialNumber;
                ?>
                <td>Equipment</td>
                <?php // if(isset($other)) { ?>
                <td><input type="text" id="txt_editotherequip" name="txt_editotherequip" value="<?php echo $otherequips // echo (isset($other->Equipment) AND $other->Equipment) ? $other->Equipment:'';  ?>"/></td>
                <td>Item Description</td>
                <td><input type="text" id="txt_editotherdesc" name="txt_editotherdesc" value="<?php echo $otherdesc //  echo (isset($other->ItemDescription) AND $other->ItemDescription) ? $other->ItemDescription:'';  ?>"/></td>
                <td style="visibility: hidden;"><input type="text" id="txt_editotherID" name="txt_editotherID" value="<?php echo $otherID  //echo (isset($other->ID) AND $other->ID) ? $other->ID:'';  ?>"/></td>
            </tr>
            <tr>
                <td>Serial Number</td>
                <td><input type="text" id="txt_editotherserialnum" name="txt_editotherserialnum" value="<?php echo $otherserialnum // echo (isset($other->SerialNumber) AND $other->SerialNumber)  ? $other->SerialNumber:'';  ?>"/></td>
                <?php // } ?>
            </tr>
            <tr>
                <td><input type="button"  id="btn_editother" name="btn_editother" value="Edit" onclick="validate_edit_otherequip();"/></td>
                <td><input type="button" id="btn_deleteother" name="btn_deleteother" class="btn_deleteother" value="Delete" onclick="validate_delete_otherequip();"/></td>
            </tr>
        </table>
    </fieldset>
</form>
</div>

这是我的javascript:

<script>
function validate_edit_otherequip(){
    if(document.getElementById('txt_editotherequip').value === ""){
        alert('Please Input Equipment!');
        return false;
    }
    else if(document.getElementById('txt_editotherdesc').value === ""){
        alert('Please Input Item Description');
        return false;
    }
    else if(document.getElementById('txt_editotherserialnum').value === ""){
        alert('Please Input Serial Number');
        return false;
    }
    else{
        var y;
        if(confirm("Are you sure you want to save updated data?") === true){
            var y = document.forms['frm_otherequips2'].submit();
        }
        else if(confirm("Are you sure you want to save updated data?") === false){
            return false;
        }
    }
}
function validate_delete_otherequip(){
    var x;
    if(confirm("Are you sure you want to delete this data?") === true){
        var x = document.forms['frm_otherequips2'].submit();
    }
    else if(confirm("Are you sure you want to delete this data?") === false){
        return false;
    }
}

这是我的控制器:

public function edit_delete_others2($id){
            $data_other['other2'] = $this->inventory_model->other_search($id);
            $this->load->view('homeview');
            $this->load->view('frm_otherequips2', $data_other);
            $this->load->view('footer_view');
}

我不知道如何在按钮中添加条件
