problema combo box
« en: 6 Marzo 2012, 02:22 am »

hola

tengo este codigo el cual trae un srting de hora asi: 14:00:00 y con un split divide la cadena en tres. el problema es que solo me esta mostrando el segundo combobox y no me muestra el primero

   $hora_cadena=split(":",$row[hora_fin]);
                  
                  
                  
               echo "<td>   
                  <select id='hf".$row[id]."' name='hf".$row[id]."''><option value='00'>H</option>
                  
                           ";if ( $hora_cadena[0] == "01" ) { echo "<option value='01' selected='selected'>01</option>"; }else { echo "<option value='01'>01</option>"; }"
                           ";if ( $hora_cadena[0] == "02" ) { echo "<option value='02' selected='selected'>02</option>"; }else { echo "<option value='02'>02</option>"; }"

Re: problema combo box
« Respuesta #1 en: 10 Marzo 2012, 19:07 pm »

las comillas en el array $row junto con la cadena dentro de los corchetes, identifican al elemento del array.

Cuando ves que una instrucción se repite más de una vez, usa ciclos/loops para simplificar el código, ejemplo:

Código
  1. <?php
  2. $row['hora_fin'] = "06:25";
  3. $row['id'] = 6;
  4. $hora_cadena=explode(":",$row['hora_fin']);
  5.  
  6. echo '<td><select id="hf',$row['id'],'" name="hf',$row['id'],'" >
  7.   <option value="00">H</option>';
  8.  
  9. for($i=1; $i<=23 ;$i++){        
  10.  
  11.    echo  ($hora_cadena[0] == $i
  12.    ? "<option value='$i' selected='selected'>$i</option>"  
  13.    : "<option value='$i'>$i</option>");                
  14. }                
  15.  
  16. echo '</select>-<select id="mf',$row['id'],'" name="mf',$row['id'],'" >
  17.   <option value="00">M</option>';
  18.  
  19. for($i=1; $i<=59 ;$i++){        
  20.  
  21.    echo  ($hora_cadena[1] == $i
  22.    ? "<option value='$i' selected='selected'>$i</option>"
  23.    : "<option value='$i'>$i</option>");                
  24. }                
  25. echo '</select></td>';

También use el operador ternario.
