不工作日期的領域正確

Question

我是學生，網絡程序員和我有一個任務我最近assigned.The以前的人誰拉着我的位置設立了一個新聞報道的網站，是一個小馬車的問題。

與網站的問題是，當您指定的日期範圍的新聞文章，以顯示它的日期，要麼恢復到他們先前否則將更改爲隨機。試圖在2010年之前設定日期是每次都會發生此問題的唯一方法。有時在出現問題之前它可以用於很多用途。

只是爲了澄清，我不是在尋找/希望有人給我一個徹底的答案/做我的工作對我來說，尤其是因爲我真的很努力學習，提高自己的技能。如果有人能指出我解決這個問題的正確方向，我會非常感激。

這裏是所有從文件中的日期我期待在引用：

// Create dates 
$year = (isset($get['year'])) ? $get['year'] : date("Y"); 
$year2 = (isset($get['year2'])) ? $get['year2'] : date("Y"); 
$month = (isset($get['month'])) ? $get['month'] : date("m"); 
$month2 = (isset($get['month2'])) ? $get['month2'] : date("m"); 
$day = (isset($get['day'])) ? $get['day'] : date("d"); 
$day2 = (isset($get['day2'])) ? $get['day2'] : date("d"); 

//create first and second dates for range 
$t_current = mktime(0, 0, 0, $month, $day, $year); // Current month Unix timestamp 
$t_next = mktime(0, 0, 0, $month2, $day2+1, $year2); // date2 unix timestamp for date range 

// Criteria 
if ($author_url) { 
    $this->EE->db -> where ($author_name_field_id, $author_name); 

$this->EE->db 
    -> where ("exp_channel_titles.entry_date >= $t_current") 
    -> where ("exp_channel_titles.entry_date <= $t_next"); 

} 

else { 
    $this->EE->db 
    -> where ("exp_channel_titles.entry_date >= $t_current") 
    -> where ("exp_channel_titles.entry_date <= $t_next"); 
}

Answer 1

在代碼中的這一點：

//create first and second dates for range 
$t_current = mktime(0, 0, 0, $month, $day, $year); // Current month Unix timestamp 
$t_next = mktime(0, 0, 0, $month2, $day2+1, $year2); // date2 unix timestamp for date range 

我肯定會添加一個檢查，以確保$ t_next晚於$ t_current因爲這將是第一個邏輯問題，我會尋找。

if($t_current>$t_next){ 
    // swap them over 
    $tmp=$t_current; 
    $t_current=$t_next; 
    $t_next=$tmp; 
} 

Answer 2

在代碼中的這一部分（注意在47行for()環路）：

<select id="year" name="year" style="display:none"> 
<?php 
//lists years 
      for ($i = 0; $i <= 3; ++$i) // Try to change this to: for ($i = 0; $i <= 5; ++$i) 
      {     
       $time = strtotime(sprintf('-%d years', $i)); 
       $value = date('Y', $time); 
       $label = date('Y', $time); 
//if year is set stay on that year   
       if($year==$value) 
        { printf('<option value="%s" selected="selected">%s</option>' , $value, $label); 
        } 
       else 
        {printf('<option value="%s">%s</option>', $value, $label);}   
      } 

這部分（注意線106 for()環路）：

<select id="year2" name="year2" style="display:none"> 
<?php 
//lists years 
      for ($i = 0; $i <= 3; ++$i) // Try to change this to: for ($i = 0; $i <= 5; ++$i) 
      {    
       $time = strtotime(sprintf('-%d years', $i)); 
       $value = date('Y', $time); 
       $label = date('Y', $time); 
//if year is set stay on that year   
       if($year2==$value) 
        { printf('<option value="%s" selected="selected">%s</option>' , $value, $label); 
        } 
       else 
        {printf('<option value="%s">%s</option>', $value, $label);}    
      }    
//first year selected instead of blank 
    ?> 

它從今年到三年前創造了一個下拉選擇。因此，當您指定年份之後（2010年之前）時，該年不屬於<select>框。 <select>同樣適用於year2。

如果您想支持更多的年份，只需將其值改爲3即可。

順便說一句，嘗試添加的開始日期< =結束日期的支票。我試了一下，雖然它沒有給我任何錯誤，但它只是顯示沒有結果，而不是說它是無效的日期範圍。
