具有相同的輸入名稱多種形式的輸出第一形式發佈信息

Question

簡單，因爲我在標題解釋我在每一個表格的最後有這樣的代碼

<input name="changety" class="chvf" type="hidden" value="1"><input name="itemid" value="<?= $result['id'] ?>" type="hidden"></form> 

，正如你看到的itemid正在導入從數據庫和有多種形式，使用此變量，但當我試圖訪問它屁股後_ $ _POST ['itemid']它總是會得到這第一個實例

我想知道是否有一種方式做這件事謝謝安德魯

Answer 1

它的原因是，隱藏變量只有一個'name'屬性，因此它越過了。

發佈的隱藏變量可能是您最後一次在循環中設置它。

你應該使用數組一樣：

<input name="changety[]" class="chvf" type="hidden" value="1"> 
<input name="itemid[]" value="<?= $result['id'] ?>" type="hidden"></form> 

而在後端PHP，做要緊。

Answer 2

爲了解決這個問題，<input name="itemid[]" value="<?= $result['id'] ?>" type="hidden">在此輸入的名稱應該，的確是一個數組，但在你的情況，我可以看到的例子，它僅僅是在年底有一個[]平原名。服務器不解釋HTML代碼爲陣，因爲HTML沒有數組而且也不該服務器爲這一問題:)

解釋HTML您需要更改弄成這個樣子：

<input name="<?= itemid[$result['create_image_1']] ?>" value="<?= $result['id'] ?> 

，也，將if更改爲if() elseif() ...語句並更改每個$result的隱藏輸入的名稱，否則輸入的值不會更改。

另一種方式是創建多個表單，其中foreach()語句對提交按鈕具有不同的名稱。在這種情況下，您需要檢查if(isset($_POST['button_name']))，其中button_name對於每種形式都會有所不同。

希望這會有所幫助！ ：D
