如何设置多个提交按钮以上传

Question

我希望上传14条记录。在上传之前我想选择相应的检查按钮。一次只能上传一条记录。因此，所有14条记录都安排在一个带有两个按钮的表中，一个用于选择文件，另一个用于提交。但问题是只上传了第一个文件，其他文件没有上传。后来我知道我必须在所有提交中使用多个表格。怎么可能呢？

     <div class="portal-body" style="min-height: 268px;">                        
                <table class="table striped hover bordered" id="sample_editable_4">
                    <thead>
                        <tr>
                            <th id="eval_style">Sl No.</th>
                            <th id="eval_style">Document Name</th>  
                            <th id="eval_style">select</th>  
                            <th id="eval_style">Choose</th>
                            <th id="eval_style">Submit</th>
                        </tr>
                    </thead>
                    <tbody> 
                        <?php  $i=1; 
                            foreach($evidence_details->result() as $row_evidence) { ?>
                            <tr>   

                                <td><?php echo $i; ?></td>
                                <td><?php echo $row_evidence->evidence_name; ?> </td>            
                                <td>
                                    <input type="checkbox" name="evidences" id="<?php echo $row_evidence->evidence_id; ?>" value="<?php echo $row_evidence->evidence_id; ?>"  <?php if(in_array($row_evidence->evidence_id,$evidence)) { ?>checked="checked"<?php } ?> />
