Question

嗨，我正在尝试在while循环中的一系列文本框中显示一些数据。我想根据上一页的选择选项来填写输入字段。如果选择的值为25，则数据应仅每四行显示一次。如果为50，则应在每个备用行中显示数据，对于100％，将显示所有值。我已经标记了需要应用所选值的条件的位置。

previous.php

<select class="form-control" name="select36">
<option value="100">100%</option>
<option value="50">50%</option>
<option value="25">25%</option>

add.php

    <?php
<!-- MYSQL QUERY -->
$sql = "select id ,code, addl_item_code_barcode, main_group, 
item_name_w_shade_category, shade_name, size , current_stock from items 
where main_group in (SELECT distinct(main_group) FROM items WHERE 
addl_item_code_barcode IN ($d)  and status='active') and status='active' 
order by  item_name_w_shade_category, size, shade_name";
$result = pg_query($db, $sql);
$counter = 1;
$i = 1;
while ($res = pg_fetch_assoc($result)) { <!-- 1st loop -->
$i++;
?>    
<td> 
<!-- THIS IS WHERE THE CONDITION NEEDS TO BE APPLIED FOR  SELECTED VALUE-->
<?php

if(isset($_REQUEST['select36'])){

<!-- FOR 100% (DISPLAY DATA IN EVERY ROW)-->  
if($_REQUEST['select36'] == 100){ 
?>
<input type="text" class="form-control"  size ="1" name="p36"  value =<?php 
echo $balqty; ?> disabled> <br>
<?php
if (isset($_REQUEST['add1'])) {
$var1 = $_REQUEST['add1'];
if ($var1 > $balqty) {
?>
<input type="text" class="form-control check-change<?php echo $counter; ?> 
saisie add1"   style="background-color: whitesmoke;"  size ="5" 
name="qty_1<?php echo $res['id'] ?>" id="qty_1<?php echo $res['id'] ?>"

<?php
}
?>

<?php
} else {
 $var1 = 0;
 if ($var1 > $balqty) {
 ?>
 <input type="text" class="form-control check-change<?php echo $counter; ?>

<?php } 
else {
?>
<input type="text" class="form-control check-change<?php echo $counter; ?> 
saisie add1" maxlength="4" min="0"  size ="5" name="qty_1<?php echo 
$res['id'] ?>" id="qty_1<?php echo $res['id'] ?>" value ="<?php echo $var1 ?

<?php
}
}
}
<!-- END FOR 100% (DISPLAY DATA IN EVERY ROW)--> 



<!-- FOR 50% (DISPLAY DATA IN ALTERNATE ROWS) -->                                                  
elseif($_REQUEST['select36'] == 50){
if ($i%2==0) {
 ?>

<input type="text" class="form-control"  size ="1" name="p36"  value =<?php 
echo $balqty; ?> disabled> <br>
<?php
if (isset($_REQUEST['add1'])) {
$var1 = $_REQUEST['add1'];
if ($var1 > $balqty) {
?>
<input type="text" class="form-control check-change<?php echo $counter; ?> 
saisie add1"   style="background-color: whitesmoke;"  size ="5" 
name="qty_1<?php echo $res['id'] ?>" id="qty_1<?php echo $res['id'] ?>" 
value ="<?php echo $balqty ?>" onchange="calculateTotal()" readonly>
<?php } 
else {
?>
<input type="text" class="form-control check-change<?php echo $counter; ?> 
saisie add1" maxlength="4" size ="5" name="qty_1<?php echo $res['id'] ?>" 
id="qty_1<?php echo $res['id'] ?>"  onchange="calculateTotal()"  value ="<? 
php echo $var1 ?>">
<?php
}
?>
<?php
} else {
$var1 = 0;
if ($var1 > $balqty) {
?>

<input type="text" class="form-control check-change<?php echo $counter; ?> 
saisie add1"  style="background-color: whitesmoke;"  size ="5" name="qty_1<? 
php echo $res['id'] ?>" id="qty_1<?php echo $res['id'] ?>" value ="<?php 
echo $balqty; ?>" onchange="calculateTotal()"  readonly>
                        <?php } else {
                            ?>
<input type="text" class="form-control check-change<?php echo $counter; ?> 
saisie add1" maxlength="4" min="0"  size ="5" name="qty_1<?php echo 
$res['id'] ?>" id="qty_1<?php echo $res['id'] ?>" value ="<?php echo $var1 ?

<?php
}
}

}
}
<!-- END FOR 50% (DISPLAY DATA IN ALTERNATE ROWS) -->  
}
?>
<!-- THIS IS WHERE THE CONDITION NEEDS TO END FOR THE SELECTED VALUE -->   
</td>  
<?php
$counter = $counter + 1;
}


    This is how it should look like


if(isset($_REQUEST['select36'])){
if($_REQUEST['select36'] == 25){
display data in every 4th row        <!-- KINDLY HELP ME WITH THIS LOGIC -->
}
else if($_REQUEST['select36'] == 50){
display data in alternate row
}
else if($_REQUEST['select36'] == 100){
display data in every row
}
}

还请记住，即使未显示数据，也需要显示空白文本框。任何帮助表示赞赏。谢谢！

我无法提供完整的源代码。

但是，我可以向您解释适用于您的伪代码：

如果100％->无需逻辑，只需为每个文本框赋值。

如果50％->进行偶数校验

else if($_REQUEST['select36'] == 100) {
 if ($i%2==0) {
  $value = 'Your-Input-Value';
 }
 else {
  $value = '';
 }

如果百分比为25％，则必须为每个第4个字段赋值。

这有点棘手。

手动运行：

0  -- No Value
1  -- No Value
2  -- No Value
**3  -- Yes Value**
4  -- No Value
5  -- No Value
6  -- No Value
**7  -- Yes Value**
8  -- No Value
9  -- No Value
10  -- No Value
**11  -- Yes Value**
12  -- No Value

在此处采用当前值1的迭代变量

将其循环增加。

将计数器移位：

1  -- No Value
2  -- No Value
3  -- No Value
**4  -- Yes Value**
5  -- No Value
6  -- No Value
7  -- No Value
**8  -- Yes Value**
9  -- No Value
10  -- No Value
11  -- No Value
**12  -- Yes Value**
13  -- No Value

现在，每一个可被4整除的计数器都具有价值。

因此，在您的循环中：

$i=1;
while (...) {
 ++$i;
 if ($i%4==0) {
  $value = 'Your-Input-Value';
 }
 else {
  $value = '';
 }
}

还有您的文本框：

<input type="text" class="form-control check-change<?php echo $counter; ?> saisie add1" maxlength="4" min="0"  size ="5" name="qty_1<?php echo $res['id'] ?>" id="qty_1<?php echo $res['id'] ?>" value ="<?php echo $value;?>" onchange="calculateTotal()" readonly>

如何仅在备用输入字段行上显示数据？
